Looks like kernel doesn't use serial console, have you provided correct 
console= boot argument?

I'm pretty sure that serial device of your board was renamed from ttyS 
to something more specific in 2.6 kernel. Check this.

Second possible reason is that you don't have boot arguments support in 
u-boot (your 2.4 kernel may have precompiled boot arguments, check 
kernel configuration).
