Yes. I have a pair of servers with 4G of RAM and both are running just
fine with a 32bit kernel. My kernel config settings are thus:

        # CONFIG_NOHIGHMEM is not set
        # CONFIG_HIGHMEM4G is not set

        # free
                total       used     free  shared  buffers   cached
        Mem:  4152908    4026344   126564       0   356584  2681860
        -/+ buffers/cache: 98790  3165008
        Swap: 2000084       2604  1997480
Now, if only I could fix LVM on there, I'd be sittin' in butter...
