Comment 5 for bug 435141

I have the kernel build just before yours and I'm running the x86 kernel and my 5300 works fine.

$uname -a:
Linux sreyan-laptop 2.6.31-10-generic #34-Ubuntu SMP Wed Sep 16 00:23:19 UTC 2009 i686 GNU/Linux

whereas yours is
Linux chundachunda 2.6.31-10-generic #35-Ubuntu SMP Tue Sep 22 17:33:14 UTC 2009 x86_64 GNU/Linux

relevant ls-pci line:

Can anyone see if this is specific to builds >= 2.6.31-10-generic #35 or specific to the amd64 kernel?
