Should I be putting this amd_msr.c ? Also, in this e-mail you say: <pre wrap="">"if there is a sane way to read MSRs without the VSA I/O on BSD" Do you mean "VGA I/O" on BSD? In orther words, you want me to disable the VGA out of the kernel? If so, I'm doing that now. Please confirm this suggestion with me.

Easy way to check is to add option "NoAccel" "true" to the card section in your xorg.conf. If that is the case, then the problem is probably in the MSR code, which I feared might give us problems in BSD. put copious ErrorF messages through the LXReadMSR and LXWriteMSR functions - the GeodeReadMSR and LXWRiteMSR functions should return error on your machine (since BSD doesn't have /dev/cpu/0/msr), but the LX_MSR_READ and LX_MSR_WRITE functions should work. One thing to check is to make sure that the inline assembly is correct and that you have I/O permission in BSD (you should, but you never know). if there is a sane way to read MSRs without the VSA I/O on BSD, then lets put that into the GeodeReadMSR and GeodeWriteMSR functions bounded the appropriate #ifdefs, which is the more correct solution (as you can tell, I know nothing of the internal workings of BSD). The problem _might_ be somewhere else, but to be honest with you, every time this failure case has come up, then this has been the problem.
