Things you need to be aware of!
The hinges are known to crack due to faulty parts from the manufacturer! Best Buy (which is where I bought the laptop) would not do anything about it! Their extended warranty doesn't cover the screen, even though the sales guy claimed it did! (Needless to say I got my money back on the extended warranty, especially after talking to Gateway and realizing that there is nothing that Best Buy's extended warranty can do for me once the default 1 year manufacturer warranty expires. Best Buy even wanted to say that I couldn't get my money back on the warranty since it was past their 14 day period, but I pointed out on the warranty that you have 1 month to return it for a full refund and the guy still had to go and talk to a manager!) Go direct to Gateway and they should replace the hinges without any issue since it is a known hardware issue and they are repairing it even if your laptop went out of warranty - according to the tech support guys I talked to.

I installed Debian testing using the rc2 debian installer, which worked without any major hitches. :)

To get the onboard nic to work, I had to use the 2.6.7 kernel or newer since the via rhineII driver would detect the card but not transmit/receive under older kernels. I have not tried anything newer than 2.4.26 in the 2.4 series, so I don't know if this was resolved in later 2.4 kernels.

To get the integrated wireless card to work, I used the ndiswrapper driver and the BroadCom windows drivers that came installed with XP home.

Use the ATI binary drivers to take full advantage of the video card and to be able to redirect your output to an external monitor.
