Hi,
This isn't the answer, but I'm attempting to provide triage for jhb who
will probably look at it.
This is a GPF, but it's not being caused by an attempt to enter
protected mode, so it isn't the most-often reported BTX issue.

It looks like BIOS code at f000:c3d4 is trying to read a word from I/O
port 0xfffa, and this is causing a GPF when it tries to write to what
looks like the BIOS data area at 0040:0058; "cursor position for video
page 4".
