High Memory - a thought...

[Jules Bean <jmlb2@hermes.cam.ac.uk>]

Having just had to add an append="mem=" line for my system, I have been
thinking about it.

I understand that the bios call will only return a maximum of 64M (I am a
little suprised no one has thought of a way of extending the BIOS...)

However, couldn't a little piece of kernel code, trapping its own
exceptions, probe memory?  Just keep accessing upwards until an exception
occurs?  And then the kernel could auto-probe any amount of memory..
