The IRQ13 is definitely not useable on an AXPpci33.
I use this patch now for ages on my system:

diff -ur linux-2.4.0-prerelease/arch/alpha/kernel/sys_sio.c linux-2.4.0-prerelease-work/arch/alpha/kernel/sys_sio.c

I don't use IDE but I need irq 10 and 15 for ISA...

Jan, another question:
can you check whether your floppy drive is actually working on a recent 2.4
kernel? Mine does return invalid data unless I '#if 0' the DMA stuff in
asm-alpha/floppy.h
I currently don't understand why it is that way :(

Bye,
Thorsten
