I don't think I have any equipment this old to test with.  I wouldn't be
suprised about this, particuarly if you are using PIO on your drive; the
high interrupt rate could be delaying sio interrupts too long.

If your hardware supports it, you can try setting the loader tunable
hw.ata.atapi_dma=1 and rebooting and seeing if it picks up the drive at a
DMA setting.
