SubjectRe: [stable] [BK PATCHES] 2.6.x net driver oops fixes

The via-rhine fix is already in the stable queue. But the sis900 oops
fix does not apply to the stable tree. It relies on a few intermediate
patches. Appears to still be an issue for the older version which is in
2.6.11. Here's a stab at a backport. Would you like to review/validate
or drop this one?

thanks,
