I dunno about that, but I was able to track the problem down... It seems
that the behavior of the request_irq/free_irq functions in the kernel
changed somewhere about 1.3.80 or so (date was Mar 27 I think) to make
them take an extra argument. Needless to say, any program calling these
functions will have problems...
Here is a patch that at least makes it compile. DANGER: I HAVE NOT
TESTED IT THOROUGHLY AND HAVE NOT IDEA IF IT'S THE RIGHT THING TO DO!
YOU HAVE BEEN WARNED!
that being said, here goes...

The problem is the extra argument, which is supposed to be a void* to
dev_id. I couldn't find any documentation of dev_id anywhere in the
kernel source tree; perhaps I didn't look hard enough? From what I can
tell from looking at linux/arch/i386/kernel/irq.c, it doesn't look like
dev_id is ever looked at, but I can't be sure of that.
I have no idea how well dosemu will work with this; I still can't get it
to work (it complains about "emumodule not loaded" and if I try to load
the module I get "gcc2_compiled undefined", "symbols from 1.3.79 don't
match those from 1.3.79", etc. I thought this problem had been fixed
already. If anyone wants to help, here's my setup:
linux-1.3.79
libc-5.3.8
gcc-2.7.2 (perhaps I need 2.7.2.l.3?)
modules-1.3.69f
dosemu-0.60.4
