>From the comments in the freedesktop bug (#205) it seems that it is really a hardware bug in the Sony Vaio computers. It may be possible to work around it, but I'm not sure in which package. It could be ACPI, which may also explain the battery behaviour.
To use the VESA driver, add the line Driver "vesa" to the Device section of your xorg.conf and restart X (e.g. by logging in and out). It's nice if you can test it, but this doesn't seem to be X-related anymore. Also, could you verify the driver version on the LiveCD you used? I see that you use AMD64 and I only checked that version 2.6.1 of the driver was included in the i386 version of 24. jan LiveCD. I saw Timo mention in an unrelated comment that it the build had failed on amd64 the first time, so it may only have been included later (it is now). I don't know if it will help exclude other things, but maybe you can start you computer in recovery mode (ESC on startup gives you a boot menu if you don't already see it). After booting into recovery mode, you can select a root shell. The computer will now run with only a minumum of services enabled. If the computer still freezes when you plug in the VGA it's definitely something low-level. It wouldn't hurt if you uploaded the files for the kernel debugging. ACPI bugs are also filed against linux.
