Does this work for you with 4G of RAM?
My boards don't support that much.. :-(
No problem.
Have to try on the AMD boards some time. But I guess if the chipset supports more than 4G you'd have to put the high_table_base to the top of low memory (default would be below 3G I guess) There's no structural problem that would disallow using the mechanism with any amount of RAM.
It works fine for me with boosted memory. It just doesn't work when the RAM stays low. Maybe I'm hitting some corner case for a 32-bit OS that doesn't want to boost the RAM outside the addressable space.
What's boosted memory?
You must, under any circumstance, keep the high_table_area in the lower 4G and you must make sure no PCI devices (or other onboard stuff) are where you'd expect memory.
