So I booted normally to F10 & kernel 2.6.34-rc2, and I have now tried to add a chainloader stanza to my grub.conf here on /dev/sda1 that will cause it to reload grub from /dev/sdb1.
Is anything missing?
Two things. Confirmation that there really is a GRUB in /dev/sdb1's boot sector and not in /dev/sdb's MBR. And you forgot to show what you added to your F10's grub.conf.
- I told it to put it in the MBR.
That would be /dev/sdb = (hd1) and not /dev/sdb1 = (hd1,0).
The string 'GRUB' exists in the MBR, but there was a grub 2 install there prior from a mint8 install.

The comment is wrong. It tries to chainload /dev/sdb1 not the MBR. The "makeactive" or "makeactive 1" typically is not necessary.
Do you see (hd1) in your F10's /boot/grub/device.map? And what does /boot/grub/device.map on /dev/sdb1 contain?
I played with that some on the f12 disk, and yes, f10's device map is in order, all bootable disks are listed in sata jack order, skipping the Terrabyte drive I use for amanda.
Thanks Michael.
