I think that different BIOS-es use different cyrix initializations
(i.e. default optimizations). One of them may have incompatibility with
delay calculations for isa cards(?) in linux. May be the begining of my
problems is one of bios updates. Anyway I sure that the problem not only
in cyrix because there are not such promlem with dos or win/nt.

May be adding some code to kernel to identify cyrix and turn
on only those features wich working fine with linux, and turn off all
others is the best solution :) ?
