I'm also using a 2.6 kernel on my R40 (working on 2.6.4 
right now), but 2.6.3 works fine for me.  Regarding the 
video card:

Make sure to compile the agpgart into the kernel (or as a 
module).  You can use the ATI one or the Intel one (I 
think).  Also, make sure to compile the ATI dri/drm kernel 
driver (but I think you got that one)

If you have a Radeon 9000, you might be able to use ATI's 
drivers from their website.  But those drivers aren't 
completely open.


Regarding USB, I had some problems if I woke up my R40 with 
the uhci_hcd or ehci_hcd modules in the kernel, or I 
plugged a USB device in after forgetting to remove the 
modules.  I'm currently debugging a problem when I shut 
down the system, but that's for another time.  Just make 
sure to compile the uhci and ehci subsystems as modules, 
and make sure that they are removed before suspending the 
laptop.  APM is good for that, in addition to having 
slightly better battery life.
