Bug Description
As discussed with pitti and NCommander, the benefits of making them built-in are:
1) to improve the boot performance a bit by avoiding modprobe these two modules
2) to avoid the nasty hacks to the /etc/modules and /etc/modprobe.d as these two modules doesn't support modalias and cannot be automatically loaded on demand
The options to galcore.ko need to be considered though:
options galcore registerMemBase
And since these two modules are normally always required for the dove kernel image, it's generally a good idea to get them built-in. The galcore doesn't support that, so have to hack into the Makefile a bit.

why do you guys think that having this driver built in will save boot time? laptop: ~# time modprobe galcore
the driver can be loaded in very short time:
root@ubuntu-
real 0m0.049s
user 0m0.020s
sys 0m0.010s
also, I see in the git that you reverted the patch the makes this driver static.
