G3 won't boot after Software Update

Question

Thanks to XPostFacto, I've been successfully running Tiger 10.4.8 on my old beige G3, with the OS installed in the first 8 Gb partition. Works great.
To get more room for virtual memory and the system, I successfully installed 10.4 from the CD onto the larger partition on the same drive. It booted OK from that partition without changing the OS installed from the CD.
However, any Software Update run - followed by the required restart - seems to kill it. I've rebooted in 9.2.2 or from the smaller partition and run XPostFacto again, but nothing seems to get the updated system on the larer partition to boot up. All I updated was Quicktime and iTunes, not the OS. (I tried going to 10.4.9 last night but started over with a clean install today.) Right now I'm looking at the blue screen and spinning daisy.
Help! I don't want to be stuck at 10.4.0

Hardware compatibility issues
Installing on a PowerBook G3, an original Power Macintosh G3, or an iMac:
If you install Mac OS X on a PowerBook G3 Series computer that does not have USB, an original Power Macintosh G3 (Beige), or a Rev. A, Rev. B, Rev. C, or Rev. D iMac, and the hard disk is larger than 8 GB with more than one partition, be sure to select a destination partition for Mac OS X that is completely within the first 8 GB of the disk.
Unless you have a PCI-slot ATA Controller or a PCI-slot SCSI card, you cannot expect to install OS X into the second partition and have it be reliable. Apple does not allow 10.4 to be installed on those older Macs, so the Installer may not check for the under 8 GB problem any more.
Mac OS X needs to be in the first under 8 GB partition. You can move your Home directories, many Applications, and OS 9 to another Drive, but not the basic system.
