I can confirm that this bug still exists in Dapper flight 5.
I attempted an install on one of these laptops last night, laptop was running the most recent bios supplied on the Toshiba website (v1.50 as of this writing). I experienced the same problems as above, you get to the partitioning step and are unable to view or modify any partition information.
I was able to get around this using the info from Matthew Garrett of:
alt+f2 (drop to shell)
modprobe -r ata_piix
modprobe -r ahci
modprobe ahci
alt+f1 (back into installer)
once this was done the installer can successfully view and edit the partitions, I was able to get through the rest of the install and the laptop can now boot normally.
