Maybe I'm missing the obvious here but have you taken a copy of whatever config file was used/generated by genkernel and used that as a jumping off point for building your own kernel. kernel's a kernel's a kernel. What it is capable of doing is in the .config file. If genkernel doesn't give you a .config file - I've never used genkernel so I don't know what it does - then assuming you have the feature turned on you can get the running config using zcat /proc/config.gz. Save that to a new .config file, put it in the kernel source directory and you should be good to go. You can also use zcat /proc/config.gz on the install CD kernel if yuo boot from that. Save it to a disk and use it as the basis for creating your own config. HTH, Mark
