(For the record) "Direct Access Frame Buffer". From Apple's Q630
datasheet,
The display memory controller in the Valkyrie IC is similar to the
DAFB IC used in the Macintosh Quadra 700 and 900 computers and to the
display portion of the MEMCjr IC used in the Macintosh Quadra 605
computer.

Unreasonable? Maybe... PDF viewers have almost certainly bloated since
early Acrobat as the format grew. But in fairness, unless these programs
are functionally equivalent, the comparison is a bit meaningless. You may
be able to find a more basic pdf viewer? (I'd give gv a shot if you
haven't already. I can't say I've tried it under etch myself...).
