I for one would like to vote for rpms of vanilla kernel build!
I have an Adaptec ASR-3410S, which is an i2o device, but since
2.6.18-1.2869.fc6, I can't use it and the i2o maintaner suggests I try a
vanilla kernel build to see if it's an FC kernel problem or a general
problem, but I don't have the skill to build a bootable kernel, let alone
give good debug info.
