1. The MCH/ICH8 hub 'requires' a minimum of 512MB to run, the board manual

128MB.
How can the Linux kernel find this out/poll this information so users do
not have to know mem=XXXXM?
I don't think it should. The Linux kernel is not trying to be
a BIOS replacement and should not know everything about the platforms
it runs on. We sometimes try to work around very common
bugs, but this one (involving lots of memory and special configuration)
seems to be more in the exotic range where command line options
or waiting for a BIOS update seem better options.

4GB of memory is $150 these days and this is a very common board *965
chipset, the bug occured with any bios > 1666P and 4GB of memory (or)
version 1612P (and possibly others) with 8GB of memory.
I guess a warning in dmesg or such would be appropriate letting the user
know of a possible work-around with the mem= option?
