- * Determine if the device really is AGP or not.

- * function detects PCI G450 cards that appear to the system exactly like
- * AGP G450 cards.
- *
- * \param dev   The device to be tested.
- *
- * \returns
- * If the device is a PCI G450, zero is returned.  Otherwise non-zero is
- * returned.

- * \bug
- * This function needs to be filled in!  The implementation in
- * linux-core/mga_drv.c shows what needs to be done.
