but the network did not start to work...

Do you use any powermanagement software (athcool, lvcool, fvcool, coolon,
athlon cooling patch, anything STPGNT related)? Does your BIOS list
anything STPGNT related?

Thanks for the hint.

If you see anything powermanagement related enabled, please disable it and
try again. Does that fix it?

I didn't found anything STPGNT related to be installed or in BIOS.

But seems that the reason for it to not work was actually stupid cable
modem, that remembered other end network cards hardware address and
refused to respond.

That solved, the 2.6.3 kernels forcedeth works, but about half of the
packets are dropped (rtl8139 used for same thing drops almost nothing).
Also it complains now very much about "unknown event 0x1" (instead of
0x21 which was complained when I tried before).
