Ah, when you said "File System is 32-bit" i thought you meant just that,
and not the filesystem io.
Checking, the io is indeed 32 bit. Also, as a further test i created a FAT
partition on hda3 (windows is on hdb1 and hdb5). Drive C was still hdb1,
but drive D became hda3 and drive E was hdb5.

My guess is that for booting it uses the bios, and is therefore fooled by
the swapping. Later on, it installs its own drivers. It automatically uses
whichever partition it was booted from as C: (which is already 'mounted'
by this time anyway, otherwise we couldn't have even gotten to this
point). It then scans the hard drives, without using the bios, and mounts
all FAT partitions as it finds them.
