Yep. See the thread "Free Unices".
I was able to get the wifi working using NDIS and the windows driver, but it only worked if there was no WEP or WPA. I went and bought an Intel Wifilink 5300 for it, but the card I got was defective, made solaris panic, and wouldn't work at all in Linux.
It works pretty good on it though, pretty much everything, even the webcam, works out of the box on it. Compiz is smooth. It's just that damn broadcom chip. I bumped the memory up to 2 gigs because ZFS eats the first 512 megs of your RAM for breakfast and I turned off swap to help the SSD
last longer. Runs great like that. I'm getting Kubuntu off of mine soon and I'm gonna put Opensolaris back on it.
