Thanks for the help so far, I got finally a bit further, and it looks
very promissing but ran into another problem. For some reason the request for
irg 58 failled.

too bad, somehow it isn't quite right in this case.

My config.opts looks like the following:

include port 0x100-0x4ff, port 0x1000-0x17ff
include memory 0x80080000-0x8008ffff

There is not statement in my configuration which forces the use of irq 58.

There has been another problem, probably not related to the one above.
In order to make the AVM A1 PCMCIA card work as much as it works now,
it needs a patch for
pcmcia-cs which includes a kernel module called avma1_cs.c. This
module uses the function kfree_s() which seems to be not available
in kernel 2.4.17-rc1-benh. I wonder if kfree is a replacement for it, although
it misses the second parameter of kfree_s()?
