Confirmed. The first on-board eepro100 is working now, with all
interrupts on CPU0; the SK98 gigabit card still works, even :)
Of course this is no solution for production use...

Is there a way (kernel parameter or something) to convince the kernel
that the bios is broken, and it should know better?

Will do so, also for other reasons - the cpqarray internal RAID code
panics with some bh=NULL trouble...

thanks a lot
