The FAT cluster size follows powers-of-two MB:
partition size cluster size
-------------- ------------
up to 32 MB 512 B
64 MB 1 KB
128 MB 2 KB
256 MB 4 KB
512 MB 8 KB
1 GB 16 KB
2 GB 32 KB
(In this list, 1 KB = 1024 B; 1 MB = 1024 KB; and 1 GB
= 1024 MB.) Regarding your partitioning plan, I'd make
the first one 64 MB rather than 32 MB (to allow for
extra typefaces, memory managers, &c.). Your third one
should probably stay below 512 MB; that would leave
your second one in the 256 MB category.

Note that the cluster sizes above apply only to FAT file
systems; the Linux file system and NTFS have "cluster"-
type structures that aren't dependent on the size of
their respective partitions. I don't know which behavior
HPFS exhibits.
Happy partitioning!
