Further, it appears that disabling tagging causes the problem
to go away (for me):

camcontrol negotiate da0 negotiate -T disabled

this can probably be done within your bios (^A on boot) to allow you 
to install. 

with the old system bios and the new system bios, this seems
to have the same value (the entire output of camcontrol negotiate
is the same) so i'm not sure what is different.
