Use modular config for AGP settings - otherwise fglrx will fail

With modular AGP like:

lsmod|grep agp
ati_agp                14988  0
agpgart                43464  2 fglrx,ati_agp

It is possible to init the fglrx module:

[  355.051133] [fglrx] Maximum main memory to use for locked dma buffers: 1764 MBytes.
[  355.051182] [fglrx]   vendor: 1002 device: 5974 count: 1
 [  355.051974] [fglrx] ioport: bar 1, base 0x9000, size: 0x100
[  355.053002] [fglrx] Driver built-in PAT support is enabled successfully
[  355.053365] [fglrx] module loaded - fglrx 8.56.4 [Dec  1 2008] with 1 minors
[  356.563679] [fglrx] Gart USWC size:192 M.
[  356.563684] [fglrx] Gart cacheable size:60 M.
[  356.563690] [fglrx] Reserved FB block: Shared offset:0, size:40000
[  356.563693] [fglrx] Reserved FB block: Unshared offset:203f5000, size:b000

This did NOT work after this change:

As this is definitely not needed to boot without initrd please use only modules and not static config for it. One example chipset with that problem (like used on Dell Vostro 1000 laptop):

ATI RS482 [Radeon Xpress 200]
