Coreboot currently doesn't support any Dell hardware.

Coreboot supports GM45 northbridges, and a few others, I'm not sure if
this northbridge is supported.
Coreboot supports the 82801Ex (ICH5) and Gx (ICH7), but apparently no

SPI flashing is pretty inevitable during coreboot development anyway (in
most cases), because internal flashing requires a booted system and
coreboot won't boot at first.
Overall, I guess this wouldn't be an easy port. And given that this
laptop is quite old, it's probably not worth it. (If you want to port a
laptop that can run without the Intel ME, I'd recommend one with GM45
