Re: Hardware Check!
You should be in luck now with 1.4 (or 1.4.1). I have the Compaq version of that laptop (R4000) and everything works.
Just about everything is ready from the first bootup. Keep in mind the video won't be that great for hardware acceleration until ATI releases the open video drivers. As far as your broadcom wifi, use ndisgen to compile the wifi drivers from the Windows inf and sys files.
FYI... If you start getting hard lockups it's probably due to the powerd command in the /etc/rc.conf. For whatever reason, it seems that the application locks up with newer AMD Sempron/Athlon 64 cpus.
Let me know if you need some help,
