Subject: [PATCH] fixed: CRC32=y && 8193TOO=m unresolved symbols

Linus,
please apply – this fixes unresolved symbols when CONFIG_CRC32=y and CONFIG_8139TOO=m (it also appeared on some other ethernet device drivers). I think this is the right way to fix this problem. It at least now builds, links and boots (and hey, even my ethernet works so it can’t all be bad :)

patches cleanly against 2.5.70 and 2.5.70-bk8
