There is a difference between SD and SDHC in the way the size of the file system is worked with internally. The SD standard uses a signed long int (in C parlance) and counts in bytes, so that the maximum size is 2GB. Many implementations accept it as an unsigned int, making the maximum 4GB (those are the 'non-standard' 4GB SD cards).
SDHC counts (effectively) in 16-byte blocks, thus the 32GB maximum.
My point is that if you support SDHC at all, there is no technical reason to support 4GB and not 8 or 16 or 32. They work the same, just like, say, 512MB or 1GB non-HC SD cards do. And indeed, they work fine technically; I'm using a 16GB one in my BeBook.
But like Dale says, it could well be 'They *work*, but you won't really like the results'. I haven't found it so, but YMMV.
