+.SH CONFIGURATION DETAILS
+Please refer to XF86Config(__filemansuffix__) for general configuration
+details. This section only covers configuration details specific to this
+driver.
+.PP
+The following driver
+.B Options
+are supported:
+.TP
+.BI "Option \*qHWCursor\*q \*q" boolean \*q
+.TP
+.BI "Option \*qSWCursor\*q \*q" boolean \*q
+These two options interact to specify hardware or software cursor. If the
+SWCursor option is specified, any HWCursor setting is ignored. Thus, either
+\*qHWCursor off\*q or \*qSWCursor on\*q will force the use of the software
+cursor. On Savage/MX and Savage/IX chips which are connected to LCDs, a
+software cursor will be forced, because the Savage hardware cursor does not
+correctly track the automatic panel expansion feature.
+Default: hardware cursor.
+.TP
+.BI "Option \*qNoAccel\*q \*q" boolean \*q
+Disable or enable acceleration. Default: acceleration is enabled.
+.TP
+.BI "Option \*qRotate\*q \*qCW\*q"
+.TP
+.BI "Option \*qRotate\*q \*qCCW\*q"
+Rotate the desktop 90 degrees clockwise or counterclockwise. This option
+forces the ShadowFB option on, and disables acceleration.
+Default: no rotation.
+.TP
+.BI "Option \*qShadowFB\*q \*q" boolean \*q
+Enable or disable use of the shadow framebuffer layer. See
+shadowfb(__drivermansuffix__) for further information. This option
+disables acceleration. Default: off.
+.TP
+.BI "Option \*qLCDClock\*q \*q" frequency \*q
+Override the maximum dot clock. Some LCD panels produce incorrect results if
+they are driven at too fast of a frequency. If UseBIOS is on, the BIOS will
+usually restrict the clock to the correct range. If not, it might be
+necessary to override it here. The
+.B frequency
+parameter may be specified as an integer in Hz (135750000), or with
+standard suffixes like "k", "kHz", "M", or "MHz" (as in 135.75MHz).
+.TP
+.BI "Option \*qUseBIOS\*q \*q" boolean \*q
+Enable or disable use of the video BIOS to change modes. Ordinarily, the
+.B savage
+driver tries to use the video BIOS to do mode switches. This generally
+produces the best results with the mobile chips (/MX and /IX), since the BIOS
+knows how to handle the critical but unusual timing requirements of the
+various LCD panels supported by the chip. To do this, the driver searches
+through the BIOS mode list, looking for the mode which most closely matches
+the XF86Config mode line. Some purists find this scheme objectionable. If
+you would rather have the
+.B savage
+driver use your mode line timing exactly, turn off the UseBios option.
+Default: on (use the BIOS).
+.TP
+.BI "Option \*qShadowStatus\*q \q*" boolean \*q
+Enables the use of a shadow status register. There is a chip bug in the
+Savage graphics engine that can cause a bus lock when reading the engine
+status register under heavy load, such as when scrolling text or dragging
+windows. The bug affects about 4% of all Savage users. If your system
+hangs regularly while scrolling text or dragging windows, try turning this
+option on. This uses an alternate method of reading the engine status
+which is slightly more expensive, but avoids the problem. Default: off
+(use normal status register).
