So the ATI GART driver from the chipset DP should match your HWID here (but doesn't):
PCI\VEN_1002&DEV_5A3F&SUBSYS_00000000&REV_00\3&267A616A&0&08: Puente PCI estándar de PCI a PCI
There's also an error (possibly) in the latest nightly graphics_a DP that might be interfering with the install:
From the mobility.inf:
Basically, anywhere you find the keystring "ati2mtag_RC410M", somewhere in that line of code you'll find these odd/funny box characters (invalid CR?).
The mobility.inf is also missing some critical entries (taken from the ASUS drivers):

I'm checking the MassStorage DP now for the IDE controllers.
*Edit
MassStorage DP is good. Your HWID is listed.
