Pedro,

For some reason, the default .config file that was generated by "make 
oldconfig" or "make xconfig" did not allow the DSDT option to be 
selected. However, when I used your .config file with the vanilla kernel 
source 2.6.9, I was able to select it and it compiled without a problem. 
I then tried the same thing but with the debian kernel source, and it 
worked also.

I think for people that cannot see the "use custom DSDT" option (most 
probably people who apt-getted their source from Debian), they should 
use your .config file (copy it to /usr/src/linux-X.X.X/.config), make 
oldconfig, then make xconfig (or menuconfig, gconfig, etc). The option 
will then be available.

Simply adding the lines:

CONFIG_ACPI_CUSTOM_DSDT=y
CONFIG_ACPI_CUSTOM_DSDT_FILE="/usr/src/linux-2.6.9/my-dsdt.hex"

to the .config file does not work, as when you run "make xconfig" or 
"make oldconfig && make xconfig" the options are not available (and if 
you immediately check your .config file, they will have disappeared!). 
Anyway, I've attached my (slightly revised) .config file and which 
should work for any Debian and RedHat users that want to run kernel 
2.6.9/2.6.10 on the X300 (the RAM is configured for 1GB, but it seems to 
work between 768MB and 1152MB as far as I can tell).

Thanks again,

Silas
