Welcome to coreboot.
Sorry for the late response, i'm not subscribed.

You need a working GX2 vsa.
As far as i know there is no ready and free available version around.
I have a version that works mostly, but i am working on a new version.
As i have very little time to spend on it it is evolving slowly.
There is no early (bios) vga available yet.
ACPI is not implemented.

This is a software limitation of the original bios.
I boot from a IDE drive in coreboot.

I don't see that on coreboot.
OpenVSA is never finished and not working.
The current state is:
I use rev.6433 with some patches for development/testing and stopped
updating because of tracing the many regressions took all my time.
I don't know if current trunk boots on S50.
Probably not as there are a lot of changes such as small bootblock.
It boots linux and when you use the in kernel geode GX2 vga driver you
can use VGA.
Power button doesn't work.
No ACPI. (no real problem when you don't use suspend)
Beeper doesn't work.
If you want an experimental coreboot rom image send me a mail.
