If I get some time over I'd like to try replacing mesa's routines with
libsysdev.

devinfo doesn't handle partitions ?

$ devinfo /dev/sda
/sys//devices/pci0000:00/0000:00:13.1/0000:03:06.0/ata1/host0/target0:0:0/0:0:0:0/block/sda/device
$ devinfo /dev/sda1

You can use:

PREFIX=/usr/local make
PREFIX=/usr/local make install

or similar to make it install in your preferred dir.

Works fine on a pure 32-bit debian.
