Um, i just figured my machine can run the Trisquel 6.0 64-bit version.
Everything works just fine, though i dunno what is going on on the graphics
side. Graphics work well, i just don't know how.
The machine is a Macbook2,1 Mid 2007. It boots in 32-bit EFI mode and loads
the 64-bit kernel. The CPU is 64-bit able:

$ uname -a
Linux MyMachine 3.8.5-gnu #1 SMP Thu Mar 28 21:33:10 PDT 2013 x86_64 x86_64
x86_64 GNU/Linux
For the graphics it says:
$ sudo lshw -c video
*-display:0

so there is some 32-bit thing about the graphics card. but the driver again
is 64-bit:
$ file /lib/modules/3.8.5-gnu/kernel/drivers/gpu/drm/i915/i915.ko
/lib/modules/3.8.5-gnu/kernel/drivers/gpu/drm/i915/i915.ko: ELF 64-bit LSB

BuildID[sha1]=0x55f457d3d49b6158a2170ed218c2520589f902fc, not stripped
please help me understand how and why this works
cheers Mono
