FBSD 8: custom kernel config ends boot at "mountroot>". Plz. help!

[Rob]

Hi,

My system boots fine with the GENERIC kernel on FreeBSD 8.0

I made a custom kernel, but the boot process then ends with the

mountroot>

error and prompt.

Apparently something is wrong with my kernel config file.

Can somebody check it below and tell me what is wrong with my kernel config 
file? Especially the GEOM_PART_* at the end might be the culprit, although this 
configuration used to work for 7.3.

Thank you!

Rob.
