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=0xf1840000 irqLine=48 contiguousBase=0x8000000 contiguousSize=0x2000000

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?
the driver can be loaded in very short time:
root@ubuntu-laptop:~# time modprobe galcore

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.
