I´ve just managed to get the 12.04 LiveCD to boot into a GUI on my MacBook Pro 5,2

/sys/class/dmi/id/bios_vendor:Apple Inc.
/sys/class/dmi/id/bios_version: MBP52.88Z.008E.B05.0905042202
/sys/class/dmi/id/bios_date:05/04/09
/sys/class/dmi/id/sys_vendor:Apple Inc.
/sys/class/dmi/id/product_name:MacBookPro5,2
/sys/class/dmi/id/product_version:1.0
/sys/class/dmi/id/board_vendor:Apple Inc.
/sys/class/dmi/id/board_name:Mac-F2268EC8
/sys/class/dmi/id/board_asset_tag:Base Board Asset Tag#
/sys/class/dmi/id/chassis_vendor:Apple Inc.
/sys/class/dmi/id/chassis_type:8
/sys/class/dmi/id/chassis_version:Mac-F2268EC8

I had to add the following to the grub menu entry prior to booting:

 outb 0x728 1
 outb 0x710 2
 outb 0x740 2
 outb 0x750 0
 set gfxpayload=keep
 linux /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper quiet splash nouveau.noaccel=1 --

I also made sure that the Power Saving settings in OS X were set to ¨Performance¨.

The screen initially goes black before eventually flickering and then showing the gui desktop. Adding blacklist=vga16fb or nomodeset, either together or individually on the kernel line resulted in X not starting and being dropped to a console.

FWIW this is being posted from the LiveCD (USB) during installation after installing the Broadcom restricted drivers and connecting to a WiFi network (802.11n WPA2 encrypted).

I´ll let you know how things go after the reboot...
