8139too suspend fix, maybe.

I'm currently trying to get my Fujitsu Lifebook P2120 laptop to suspend/resume successfully, and the first stumbling block I've come across with a plain Linus bk tree is that while the 8139too driver is up and running, the kernel thread it starts doesn't suspend. The attatched patch fixes this; I have no idea if this is correct, but it works.

Getting the radeonfb to resume is the next problem . . .

See the acpi mailing list archives for someone who has solved that.

Good luck,
