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

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

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

Works fine on a pure 32-bit debian.
