xfree86 isn't setting mtrr registers
I'm running Xfree86 4.1.01. kernel 2.4.17 Debian 3.0r2 (woody). I built a kernel with mtrr support, and dmesg contains:
mtrr: v1.40 ...
mtrr: detected mtrr type: AMD K6
Also, /proc/mtrr exists.
X isn't, however, setting up the registers (/etc/proc is empty). On an earlier install of the same system (hardware, software) it worked fine, but I reinstalled, and now it doesn't. Any ideas?
