dmi_scan.c doesn't compile in-kernel (ticket 1002) for at least one person, dmi_scan.c doesn't compile as a module, but it works for me (tkt 1002) i2c-elv.c doesn't compile for 2.2 kernels because of __exit (ticket 1005) I'd like to look at these more this weekend and put fixes on the home page before we do the freshmeat thing.
