 well - when attempting to boot from the memstick images I can
 clearly see everything - the whole 'BTX loader' stuff and everything
 up to and until the 'Welcome to FreeBSD' boot menu. Up to this point
 everything looks really ok. The 'messed up display' starts right after
 pressing '1' to boot.
 
 Shouldn't it show the 'BTX loader' stuff garbled as well then if they
 don't care about legacy VGA modes then?

 Just re-checked on this. Those boot options are 'disabled' by default
 (and disabled as well in my setup). According to the inline BIOS help
 they won't do any magic beside not showing the fancy Intel logo graphic.
 They too state clearly there that this won't affect capabilities when it co=
 mes
 to boot the OS.
 There aren't any more video optimization inside the BIOS.
 
 Please let me know if I can be of help to get this sorted.
 
 cheers,
