in early probe code under the bus.h system. Make debugging runtime
configurable. Some s/u_char/u_int8_t/ work. Set ia_iosize to a sane value.
Move wds_init up before the setting of the DMA machinery to cascade mode (from
Charles Hannum). Add ISA bounce-buffering code inside #ifdef notyet. In the
-ASC case buffers could never be gotten due to forgetting some braces, added
them. Removed a possibility of a NULL deref in some diagnostic printouts.
Unmap the I/O area after the probe. Cache the bustag and the iohandle in
wds_init. Did set WDS_IO_PORTS to 8 as some code indicated it might take up
that much even though I only know of three ports in there.. This might be
changed down later again.
