Since then I have made some progress;
- Installed version 5.1 again
- I noticed in the kernel logging, that the PCCARD was using IRQ1 (???)
---dmesg-snip---
Using $PIR table, 5 entries at 0xc00fdf70
pcib0: <Host to PCI bridge> at pcibus 0 on motherboard
pci0: <PCI bus> on pcib0
cbb0: <TI1221 PCI-CardBus Bridge> at device 17.0 on pci0

atkbd0: <AT Keyboard> flags 0x1 irq 1 on atkbdc0

---snip---
- Recompiled the kernel without any pccard support
This solved most of my problems; the keyboard was functioning as normal now,
but I don't have any
functioning pccard anymore. As soon as I insert the driver (as a module now)
the driver gets IRQ1 assigned :(

cbb1: <TI1221 PCI-CardBus Bridge> at device 17.1 on pci0
pci_cfgintr: 0:17 INTA routed to irq

My question now is, how is it possible that the driver (cbb) gets (via the
pci-bus) a reserved IRQ1 assigned, which is allready (rightfully) in use by
the keyboard driver. I have taken a look in /dev/pccbb.c and accompanying
files... but allas I'm not a programer...
Kind regards (and sory for such a long post),
Hein Hermans
