The limit is the kernel ...  kernel limit is ( actually 2.6.20.4 ) 64GB of 
ram , IMHO the actual HardWare Limit.

you can check it in your kernel config, if you don't have the kernel sources 
maybe you have config.gz support in proc , check it in /proc/ if it's there 
you can check this way :
tar -c /proc/config.gz | grep CONFIG_HIGHMEM

there you'll your answer.
