I'm in Window$ now( developing in Flash, sigh!), can't check the irqs.
But I remember that I checked for this and the irqs were different.
It's also interesting that I got half the latency switching from
kernel-2.6.10 to 2.6.11. The latter is x86_64, BTW. And I can't get such
low latency on MacOSX or XP (neither with the Egosys PCI card). And this
is a USB card.
