> Have you tried "Generic PCI IDE Chipset Support" ?

I thing that you are about:
generic / default IDE chipset support (kernel 2.6.10) ?
Probably in 2.4 series the name was as you quoted.
Yes. This option was compiled in kernel.

All kernels were compiled with setting all chipsets.
I cared about set all of options responsible for IDE.
All IDE drivers was compiled into kernel (not modules).

Part of my last config (2.6.10):

I think that the solution of my problem is here:
http://marc.theaimsgroup.com/?l=linux-ide&m=109967556605057&w=2
and here is your response:
http://marc.theaimsgroup.com/?l=linux-ide&m=109969178814722&w=2

"AFAICS this option allows users to use generic code for
unknown/unsupported devices which can result in unpredictable results
(hangs, data corruptions)." BZ

So I tried to apply this patch to 2.6.10rc1 kernel but there was a
problem to compile it. I couldn't compile even clean 2.6.10rc1 without
this patch.
I analised this patch and changed manualy
drivers/ide/pci/generic.c
drivers/ide/pci/generic.h
from vanilla 2.6.10.
And ... nothing happend. The kernel was compiled cleanly without
errors, but this didn't solve my problem.

Any suggestion?
