Apparently the last probe function called before the crash is reiserfs_probe(),
which seems to corrupt the stack. After disabling the registration of reiserfs
I get:

| Disk geometry for /dev/hda: 0.000-1039.500 megabytes

| 6        424.758   1039.500  ext2        

Which is consistent with the data from HdToolBox.

After re-enabling affs and adding support for MultiUser (patch below), I get:

:-(

For /dev/hdb, which doesn't contain any affs partitions:

| PROBING FOR AN AMIGA PARTITION TABLE.

Which is OK.
