I agree. I am currently looking for a laptop and took a FreeSBIE 1.1 CD 
with me to several places (Best Buy, Circuit City, Staples, and 
others...) and every Compaq or HP machine (not just AMD64, but every 
one!) shutdown when I tried to boot. It didn't matter which selection I 
made from the boot prompt, they all caused a shutdown. I didn't have a 
version with the mentioned patches, but it would definitely open up my 
choices in laptops if they fix this problem. I would think this would be 
a higher priority to fix than it is. I was very surprised when I started 
looking around for information and saw that this has been a problem for 
quite some time. Unfortunately I don't have the experience to fix this 

Please note I am NOT knocking FreeBSD in any way. I run 5 on my current 
laptop (it is fantastic) and 4.stable on several desktop and servers 
(also fantastic... the OS, not my ability to run it). I really 
appreciate all of the hard work that everyone does for the OS. I just 
thought with the popularity of HP/Compaq machines that this would be 
fixed quicker than it has.

I'll have to try the FreeSBIE CD at work and see if this problem exists 
on desktop HPs.
