The SD hardware in a 3200 does not support SDHC so, the 750 won't have support for it either.  The SDHC specification were announced only two months before the 3200 was released.

Not sure about the driver support in r121 but, beta3 does not have sdhc driver support.

Does this mean that SDHC is hardware incompatible with old SD hardware?
I hope that SDHC need only new software.

This tells me that it is hardware specific...

Solid-state memory specialist SanDisk will this month ship its first 4GB SD card, based on version 2.0 of the SD standard, also known as SDHC. The company said it plans to bundle the card with a compact USB adaptor - handy given the paucity of devices with SDHC slots.

SDHC is not backwards compatible and can only be used in an SDHC host device. You can use regular SD media in an SDHC host device.
