I had issues getting yoper to work on my laptop as well... come to think of it it didn't work on my new mobo either... it seems really finicky about what hardware you can use, because my old mobo ran like a champ. Now it won't even boot properly. always freezes halfway through install boot no matter what kernel options i specify. I gave up on Yoper because of it. Debian and Gentoo both work fine on each of my machines.
