He said it was a 1542CF... That means that IRQ and several other
parameters are controlled from the BIOS setup screen (Press Ctrl-A and
configure away). The same applies to the CP cards (Plug'n'Pray version of
CF).
Admittedly not all things can be controlled from the BIOS, there's still a
DIP block (not jumpers) for I/O-port, BIOS address, BIOS disable and PnP
disable for the CP cards, but the rest is under software control.
Anyway, are you sure they really had two IRQ switches, my recollection
was that it had multiple DMA jumpers that you'd better get
self-consistent, but only a single IRQ jumper to set. Admittedly it's
probably at least 6 years since I last saw even a B card (and at least
a year even for CF/CP cards).
(Presumably all C type cards have this, but I've never seen a plain
154xC, but I think there were ones for a while).

Sounds a lot more likely.
PS/2 mouses uses IRQ 12 for examples, and you can get into a conflict
with the interface even without a PS/2 mouse plugged in. Disabling it
in the BIOS usually frees up IRQ 12 but...
