I put this new grub efi, with the following grub.cfg entry, into my /efi/grub folder under the MacOs partition (using rEfit to boot). ====================================================== set debug=video insmod efi_gop menuentry "Linux (2 cores) - without bios dump)" { search --file --no-floppy --set=root /vmlinuz fakebios linux /vmlinuz root=/dev/sda4 video=efifb initrd /initrd.img } ====================================================== My macbook 5,2 is booting with both kernels, acpi, and the 4Gb of RAM. Suspend and restart work. I am using Ubuntu Natty, default shell, 3d effects, "32 bits" kernel 2.6.38-11 and nvidia drivers (suggested by ubuntu - 270.41.06). I installed this Linux from the standard 32 bits Desktop CD. Screen brightness doesn't work now, but I remember some time ago that it took me a while to get it working but it can be done. The bug that you mention about the CPU throttling is not happening here, I can change the speed and it gets reflected in the right place (based on what the bug explains): $ sudo cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq 2128000 $ sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq 2128000 As one can always ask for more..., this is the output of free: total used free shared buffers cached Mem: 2829980 929848 1900132 0 78112 351680 -/+ buffers/cache: 500056 2329924 So it's not 4Gb (as far as I can see) but I am sure they are somewhere down there... I am glad to help to anyone giving more info about my system.
