I believe the 1000 is very similar to the 901?

I have FreeBSD 8 CURRENT booting and running on a 4GB SDHC my 901 (cmd line only at the moment - not enough space for KDE etc).

Most stuff works, except the Ralink RT2600 wlan. Haven't tried the camera but I have no reason to expect it to work. BT - dunno never tried it.

8-CURRENT worked better for me that 7-STABLE, as of last week. S3 standby didn't work, and there was a problem with the wired LAN.

Good luck!
