[Wlug] A question about KMS API's

Anyone know anything about the KMS API? From userland? I'm working on a project and would like to use KMS/FB directly, as at boot there will be no binaries available except ours, No libc even. Just a few static binaries. if anyone could point me in the right direction, it would be greatly appreciated it. I can't seem to find anything on it on google, and I really don't have the time to go pouring over the kernel source.
