unable to install cuda 5.5 on fedora 18 - has anybody succeeded.

I had some fun disabling the nouveau but that is done now ok.
The problem i now face is neither of the two install methods (rpm versus run) succeed.
The .run method finds the kernel source ok but then has a compile error “void not ignored as it should be”.
The rpm version runs great but now my machine doesnt boot. Last line in the boot script says “Started LSB: DKMS kernel modules installer sevice” no errors logged.

Has anybody successfully installed cuda 5.5 on fedora 18 ?
If so what did you do :-) ?
My hardware : asus rampage extreme + gtx690 + gskill 32gb kit.
