There are some non-standard SD cards with 4GB.  I've got one in my N800.
I'm sure it isn't SDHC because (1) it doesn't have the SDHC logo, and
(2) it worked before the official kernel update that added SDHC support.

Why are SDHC cards limited to 32GB?  It's not a filesystem limitation --
FAT32 supports up to 8TB, if I can trust Wikipedia.  And SDHC cards
use sector addressing instead of byte addressing, which hints at a limit
of at least 1TB (2GB limit of standard SD cards * 512 bytes per sector).
