	No. I've seen myself that disabling PS/2 mouse
	in BIOS doesn't leave IRQ12 for you -- last time
	that was on Packard Bell 486 box, with Phoenix BIOS,
	when we tried to install second AHA-1542 in it.

	Despite of disabling PS/2 in BIOS, 1542 did all kinds
	of strange and mysterious things ("going to polling
	mode", loosing interrupts, etc.) until we moved it
	from IRQ12 to some other one.

Best regards,
