Welp i went back and noticed my stupidity (thanks to many emails notifying me of it)
now the code is in fbmem.c only. I changed it to make only numerical entries in /dev/fb
and link them as fb<device number> in /dev. It also now only creates entries for the devices
you have. Works perfectly on my box. If anybody has any complaints, suggestions, objections
tell me. If something seems wrong, it probably is so tell me.
Sincerely,
Mark Guzman
