Thanks for the patch!!!
I finally got time to apply it this weekend, and plugged my FlashPoint back in, and it seems to be working like a charm. I should check for the reset messages to see if it's having to do this stuff, but I suspect that it is, because without the patch, I usually couldn't even get the system to *BOOT* with the FlashPoint installed.
Just my $.02 worth...
