Any idea if XP can cope with partition tables that use a 32-sector, 128-head
geometry rather than the default 63-sector, 255-head one? That seems to
be what some flash memory cards are using and it would make any cylinder
aligned partition also 4096-byte aligned, at the cost of moving the
1024-cylinder boundary from 7.88 GiB to 2 GiB.

Do we know of anything that requires 63s/255h?
