The profile looks bogus. The NIC driver is nowhere in sight. Normally
its mmap IO for interrupts and device registers should show. I would
double check it (e.g. with normal profile)

Actually, oprofile separated out the acenic module from the rest of the kernel. I should have included that breakout as well. but it was only 1.3 of CPU:
1.3801 0.0000 /lib/modules/2.4.18+O1/kernel/drivers/net/acenic.o
