Improbable. IRQ 14 has always belonged to the HDD. These days IRQ 15 is 
used for the second EIDE port.

With PCI, IRQs are sharable anyway, though I have to say I have some cards 
that fight.

Urk!!

seek times are not the problem. CPU usage is likely to be, and the EIDE 
drives I've seen don't default to using DMA on linux.
