They also have an interesting habit of dropping support for chipsets 
without telling anyone.  The 97xx dropped support of the 440go chipset and 
there was no mention of it in the readme or on the website.  (Which is 
what I have in my laptop.)

Keith Packard being one of them.

The hard part here is the desire for 64bit.  Intel seems to have made it 
as difficult as possible to determine if a processor is 64-bit or not.

At some point I need to replace my 3 year old laptop to something that 
will last another three years.  It looks like it is going to be as 
difficult now as it was when I bought the last one.

Another issue with the Intel chipset is that you cannot just go out and 
buy an Intel video card.  It has to be on the motherboard or an OEMed card 
that came in the machine.  (Onboard video usually gets disabled by anyone 
who wants performance because they use "shared" memory in most cases. Even 
worse is when they pad out dedicated ram with shared memory, which can 
cause striping effects on output.)

So far there are no real good options for video. If you get the video card 
with open source drivers, you are limited in what processor you can use 
and what motherboard you can buy.  For some hardware configurations, you 
have no open source options if you want fast graphics or hardware 
acceleration.

It bites but it bytes.
