I'm not convinced that this isn't an EFI system.
The CD used here looks like it was booted in EFI mode:
[ 0.000000] Command line: BOOT_IMAGE=/casper/vmlinuz.efi
file=/cdrom/preseed/ubuntu.seed boot=casper only-ubiquity quiet splash ---
And that there was some EFI data available to the system as ESRT:
[ 0.000000] efi: EFI v2.31 by American Megatrends
[ 0.000000] efi: ESRT=0xbbf56898 ACPI=0xba7df000 ACPI 2.0=0xba7df000
SMBIOS=0xf04c0 MPS=0xfd4d0
[ 0.000000] esrt: Reserving ESRT space from 0x00000000bbf56898 to
0x00000000bbf568d0.
So we may be either running into a buggy implementation, or one of those
32-bit firmwares for a 64-bit system.
Could you please tell us what the make and model is for the computer on
which you've received this error message? From this information we may
be able to track down whether it's a known issue on that hardware.
