i have successfully built and booted a config derived from your config, 
on similar hardware. The only change is that i switched on some drivers 
by default and turned off some - the modified config is attached. Could 
you try this modified config, does it boot fine for you? (One crutial 
difference is that it uses CONFIG_SATA/PATA instead of CONFIG_IDE, so 
you might have to change /dev/hdax to /dev/sdax in your /etc/grub.conf, 
for the entry of the _new_ kernel only - if your system is not fs-label 
based.)
