I believe it is ok. The number of irq's is not really based on NR_CPUS but the number of IO_APICS. But I can't say for sure as I've been solely focused on 2.6.27 and haven't been following the breakup of NR_IRQS, NR_IRQ_VECTORS and NR_VECTORS and how they are used in various places. Btw, the biggest problem I found with increasing NR_CPUS was overflowing the stack, though I doubt increasing to 96 or 128 will trigger any of the hot spots fixed in 2.6.27.
