kernel 2.4.x not booting on Dell Latitude XPi

Hi,
I have compiled a 2.4.18 kernel (and other minor versions too) and when I
choose it in lilo it just reboots, theres no output to the console at all.
I dont know what Im doing wrong, it does that whether I choose the Dell
Laptop option in the "Processor type and features" section.
If you need any other information about the hw or kernel config, just ask.

Thanks
-Mat
