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 drive.
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).
