the exact number would be interesting. i've added a field
to '#P/irqalloc' on my kernels that is the count of interrupts
per vector:
; cat '#P/irqalloc'
3 0 0 debugpt
7 0 0 mathemu
8 0 0 doublefault
9 0 0 mathover
14 0 0 fault386
15 0 0 unexpected
16 0 0 matherror
50 18 18822033321 clock
51 19 0 lapicerror
63 31 0 lapicspurious
65 1 2 kbd
73 9 772061679 ether0
81 10 8689592 ether1
89 11 11583013 ether2
97 4 5092 COM1
105 14 5 sdC (ata)
perhaps this would be useful. you can pick it out
of ftp://ftp.quanstro.net/other/kernel.mkfs.bz2
in pc/trap.c.
