Meanwhile I've found the source of the problem. A simple change in drivers/char/pc_keyb.c line 73 did the trick. - #define kbd_controller_present() 1 + #define kbd_controller_present() 0
The only backdraw I've noticed so far is the problem that the kernel won't work on servers with a ps/2 keyboard controller anymore (of course) properly. But that's a minor issue.
We are still running 2.4 kernels because our application is incompatible with the new thread library. A migration is already planned but that takes time, alot of. I don't expect a migration to take place before the end of the year, maybe even later.
