You have run mkelfImage on that bzImage?   Possibly you don't have
serial console support compiled in.  Or possibly you are probing
for ISA devices in a way which fails under LinuxBIOS.  (That is rare
but I have seen ISA device probes kill a booting kernel).

What kernel is this that you are having problems with?

To go much farther on the debugging the easy step to do is to
get an early serial console patch and apply that so you get some
kernel output...
