I've only been using the open source drivers.  But all is working OK 
now.  Here is how my kernel is configured:

CONFIG_AGP=y
CONFIG_AGP_ATI=m
CONFIG_AGP_INTEL=m
CONFIG_DRM=y
CONFIG_DRM_I830=m
CONFIG_DRM_RADEON=m
CONFIG_FB_RADEON=m
CONFIG_FB_RADEON_I2C=y

It isn't quite obvious to me why the intel-agp modules works and not the 
ati-agp module, considering the T40p has an "ATI Technologies Inc Radeon 
R250 Lf [Radeon Mobility 9000 M9]".  But putting intel-agp in my 
/etc/modules seems to do the trick (the radeon module gets loaded 
because of this).  Is the R250 an intel chip?

One thing I don't quite get it why intel-agp is used rather than the 
actual module name of intel_agp.

As for the USB problem, it seems to be a particular thing with gphoto2 
and someone has already pointed it out to the kernel list:
