I suspect your test setup isn't actually producing interrupts. Try not loading your driver and running your trigger: dmesg should overflow with 'IRQ 10, nobody cared' messages.
Or, check 'cat /proc/interrupts' to see what it thinks is on those interrupts, they may be routed elsewhere internally. What kind of bus are you triggering on? If you're using ISA, make sure you assign those interrupts to ISA in the CMOS.

LSDEV(8) Linux System Manual LSDEV(8)
NAME
lsdev - display information about installed hardware
SYNOPSIS
lsdev
DESCRIPTION
lsdev gathers information about your computer's installed hardware from the interrupts, ioports and dma files in the /proc directory, thus
giving you a quick overview of which hardware uses what I/O addresses and what IRQ and DMA channels.
OPTIONS
None.
FILES
/proc/interrupts
IRQ channels.
/proc/ioports
I/O memory addresses.
/proc/dma
DMA channels.
BUGS
lsdev can't always figure out which lines in the three examined files refer to one and the same device, because these files sometimes use
different names for the same piece of hardware. For example, in some kernels the keyboard is referred to as `kbd' in /proc/ioports and as
`keyboard' in /proc/interrupts. This should be fixed in the kernel, not in lsdev (as has indeed happened for this particular example).
The program does however try to match lines by stripping anything after a space or open parenthesis from the name, so that e.g. the
`serial' lines from /proc/interrupts match the `serial(set)' lines from /proc/ioports. This attempt at DWIM might be considered a bug in
itself.
This program only shows the kernel's idea of what hardware is present, not what's actually physically available.
