No problems with AData Class 6 8GB SDHCs (I have one in each slot) and the SDHC-patched kernel. Got 'em from Newegg. I'm using them FAT-formatted as they came, for the moment. I've had them for a couple of weeks.

Writes range from 4.9-5.6 MiB/sec (5.1-6.1 MB/sec) averaging 5.3 MiB/sec (5.6 MB/sec)

Tested reads using 2GB files with timing around a dd command like:

These reads run 11.5-11.8 MiB/sec, averaging 11.7 MiB/sec (12.3 MB/sec).

The N800 sees 7,894,528 1024-byte blocks on these, as formatted from the factory. I can read and write all those blocks, with dd at least.
