that 2 cards limit was primarily meant for E400P or T400P, not the X100P
(not sure if it'd be IRQ dependent because both the X100P and the E400P
would take a single IRQ each, i think it was more a CPU thingy) ...

I've successfully put upto 5 X100P in one box, with no problems, and
sharing IRQ is no problem either (as long as youre not using archaic
XT-PIC and not sharing IRQ between two zaptel devices) with IO-APIC it
really makes a difference, or possibly I haven't tested it too much, but
it seems to be working for the last 4 odd months

if you've got a decent motherboard, give it a shot, it'd be fun to see 6 
X100P in one box, but as others have rightly pointed out, that may not be 
the most cost-effective route and you're getting into T1+cb territory
