Hmm.  Maybe his *does* have something uncivilised on the high 
interrupt?  It'd be nice to have a generic probe-time 
test-for-an-interrupt function, along the lines of what the sio(4) 
driver does to test the interrupt function of the 8250.

Sorry, I will clarify.  There are two interrupts that I make available 
for PCCARDs, 9 and 10.  These are declared in /etc/pccard.conf, and are 
not used by anything else in the system.

Older kernels allocate IRQ 3 to the pcic, and the newer top-down code 
allocates IRQ 11.  Both of these seem to work, insofar as card 
insertion/removal events are signalled as expected.

I was just trying to give you a "feel" for the vintage of working 
kernel.  I'm just cvsupping the 2.2.5 tag monster; once that's finished 
I'll be building a batch of kernels to see where things fell down.

Qool.  If there's anything I can help with testing, let me know.
