Whelp, I'm was looking like I was going down in flames again, as things started to to all to heck again...but looks like I saved it.
I was going to apply the new update.zip w/the stock fonts, and launched ROM Manager to apply that zip... ** but ** I got a prompt that there was a new version of Recovery available (I had flashed back to older 1.8.1.3 previously to resolve the issue when the Droid won't boot into recovery).
Anyway, allowed it to flash to 1.8.1.4 CM Recovery (realizing as I hit "OK" that it was probably a mistake to do so) and then (of course) would not boot into recovery.
Then I rebooted it and (just like other times) the Droid was misbehaving, not responding, locking up. I rebooted three times, and it was looking like I wasn't going to be able to get the Droid up and running again w/out extreme measures.
Finally changed my tactics, and rather than waiting several minutes after reboot to try to give the Droid time to settle, I instead jumped in immediately as soon as the SD card mounting was done after boot and launched ROM Manager and was able to get to flash 1.8.1.3 recovery just before it locked up again. (felt like a Mission: Impossible race against time).
Then pulled the battery and rebooted successfully into recovery, applied the default fonts zip, and rebooted and let it sit for 10 minutes to allow it to settle.
And voila, I appear to be up and running again.
So Fab, your update.zips are my holy grail at this point...gonna always keep one around to rescue me when things get dark and scary...
And thanks again for the default fonts...easier on my wimpy eyes.
