I think you're irritated about the wrong thing.  The RTC-memory 
cannot (in any standardized way) indicate more than ~65MB of 
system memory.  This means that bypassing the BIOS and groping 
around in the RTC-memory is a dead-end solution.

There are standardized BIOS calls to obtain the correct amount of 
memory, even when it exceeds 65 MB.  I think the boot loader should 
make these BIOS calls and pass the correct information to the kernel.
