gentoo-sources intalls its modules under /lib/modules/2.4.22-gentoo-test-r1. I guess this was carried over from gentoo-test-sources. I think it should be /lib/modules/2.4.22-gentoo.

It seems to be fine now [ with Makefile MD5 14d1d85aee5336d21a902a63e42d8935 ]...
yes, this is fixed, thanks for the bump
