Quest for the holy Grail/not really/ trying to find/inst kernel devel, nforce

[mikey0000]

hey ive gone from fedora to mandriva to debian. I think ill stick with debian becouse of the vast amount of packages.

ok can anyone help me find the kernel devel for debian 4.0 i think it is as i want to install the nvidia video drivers (as i will be receiving a graphics card soon)
i currently am not connected to the net becouse i cant manage to install
nforce 405 drivers for my lan, which is with the forcedeth.c
and the rest i also only get trys at getting on the net so i cant check anything without carting my pc to a ethernet port which is about 3 doors and 2 flights of steps away lol.
, i also cant convert any of the rpms to .deb with alien as it errors saying i need (resonable list) of key files.
so anyone keen on helping this noob,

also do the rpms have to be noarch or not??

etch is the debian type im running and it was from downloaded dvds, ive managed to convert rpms to .debs but i still get error messages well i think their error messages.
