Yes! Mostly... 2.6.23-rc2 has a "temporary" patch applied, which should
work by itself (at last it works for Marcin). So, it's very good news
it works for you too. But, as a matter of fact the other patches
(I hope you mean these yesterday's two) probably are not used very
much (the last one could do some work but with other irqs).

So, it would be interesting to try them with e.g. 2.6.23-rc1. But not
together (I'd remind that after applying such a patch, make oldconfig,
make and so on plus testing, you can revert it with the same command
you used to patch plus -R option (e.g.: patch -p1 -R < ../patch1.diff),
to save some time on restoring a 'vanilla' kernel version.
The aim of these newer patches is to find why exactly this patch in
-rc2 works...

Cheers,
