I'll be doing this again one day (possibly 'soon').
The one thing I convinced myself of (heh) is that when
running the shell script that grub uses to write the MBR
(or what-have-you) .. the *only* write-able drive on the
system should be that USB pendrive, and no other.
This means disconnecting cables from all other mass
storage present, except the (probably ATAPI) CDROM
Maybe this is old hat now; or maybe people don't
agree -- I'm almost certain that's how I did it.
Once the USB stick's MBR (and friends) are properly
GRUB'bed, then things can proceed more simply;
reconnect those cables to other devices (IDE bus
for the other hard disks). BIOS selects how the
system responds to presence of the USB stick.
In this way I had no problem dual-booting a VIA
EPIA ML6000EA either off an IDE flash drive or
the USB stick -- even blind (USB in, it boots; USB
pen drive out -- the IDE flash drive boots: no VGA
display connected, no problem).
