mtrr and ioctl - will patch help?

[Jim Cornette]

I was reading up on mtrr and ioctl because of a problem that I have with 
starting X up when my computer is first booted. Google brought up this post.
Subject	PATCH: fix bogus ioctl return in mtrr

This is fairly self explanatory - ENOIOCTLCMD is an internal code 
outside of the -1 to -511 range. The correct return for an unknown ioctl 
is -ENOTTY
although some Linux devices return the incorrect -EINVAL result.

My trouble seems to be with my video memory taking a long time to set up 
correctly.

Anyway, is there going to be a patched kernel soon to test?

no that patch won't help you, if you get into that path you get an error
no matter what, it's just the exact error value that was incorrect.
