You can also add a chainload from the Grub config in sda to load the Grub install on the USB drive. You will have to remap the drive as part of the stanza so that the USB drive becomes BIOS drive 0.

Thank you for the words of wisdom Mikkel and Mike. I have to think about this a bit, because I have installed (on a server) FC8 (32 bit) on one drive and 64 bit on another, using the 32 bit sda MBR and boot partition and just pointing to the sdb boot from the boot partition on sda. But I will be careful not to botch the existing install, and if it doesn't work as expected I'll play with the remap. My plan is to get the FC9 boot by just manually selecting an alternate stanza of the grub.conf, but if that doesn't work I know what to try next.

On your setup, you will have to change things slightly - my stanza was for a system having only one drive. For you, you would need:

title USB boot
     map (hd0) (hd2)
     map (hd2) (hd0)
     chainload (hd0)

You also have the option of telling the BIOS to boot from the USB drive...
