Hardware-wise, XC is HC. Wikipedia has more details.

At least the N800 does handle SD version 2 - so SDHC up to 32GB... and I think the hardware could in theory support XC - but not at higher speeds and possibly not without software/firmware support. I'd love to be proved wrong
There are some reports of working cards here.

Speed-wise, Nokia disabled high speed (either 24 or 48MHz) support in the driver as it caused problems with some cards (and I was also too chicken to re-enable for everyone in the CSSU), but there are simpe patches to re-enable it around for those who need the extra speed and know what they are doing.

(As a side note _ I have several USB adaptors that support SDHC, but really annoyingly not SDXC.)
That's because the SD driver runs on the embedded controller inside the adaptor and can't be updated :-(
