Kernel sources are not included on the recovery CD, you have to download them
manually. Once you got the sources on your Cobalt box the kernel can be built
as usual (see e.g.
http://www.mclink.it/personal/MG2508/nbsdeng/chap-kernel.html). Also please
note that the LCD patch mentioned in the email cited below is only applicable
to 1.6 kernel. -current has LCD support by default.

Hope this helps,
