One of our customers has a Fujitsu laptop, poor thing...
It shares IRQ10 between Eepro, additional IDE for CD-ROM (CMD646),
and USB controllers. I talked this over with DaveM briefly,
and if I understood him right, something like the attached
patch may be in order. Anyone cares to comment?
Thank you,
