I read that you can download the previous update from their website onto a USB key and insert it into the PS3. Restart the PS3 in Safe Mode (hold the power button until it beeps twice and reboots) and an option should appear to install the update from the key.
Hopefully this will help some of those PS3 owners that are affected. I like to think Sony will reimburse owners suffering from this.
