No, you're wrong.  Unless you've got APIC running, if your Linux 
box is x86, you're still carrying baggage from 1981.  Namely, the
limited number of IRQs. 

This problem has been mitigated over the years, first, partially,
sometimes, after much waving of Dead Chickens, by Plug-n-Pray, and
then by PCI, and then by OSs that allow IRQ-sharing.

Even then, though, the Dead Hand Of 1981 hangs over Linux: perform-
ance suffers if too many PCI devices (whether cards or devices built
onto the mobo: IDE, USB, ieee1394, SCSI) share the same IRQ.

Spit in one hand, and wish for peace in the other.
Guess which is more effective...
