I have a good idea what this problem is (espically if it is APM
related).  I was working on some patches for it at the weekend, but
haven't finished them yet.  Can you add have a look at the PR:

	http://www.FreeBSD.org/cgi/query-pr.cgi?pr=28418

there is a patch for /usr/src/sys/i386/i386/i686_mem.c which
replaces 3 lines saying "wrmsr(msr, msrv);" with:

	if (omsrv != msrv)
		printf("MSR %x, old=%llx new=%llx\n", msr, omsrv, msrv);

if you could apply this patch, recompile and install the kernel and
then send me what gets printed on the console when you start X that
would help.

	David.
