'cutmem' != kernel 'mem'

[Alexey Kuznetsov]

Hello!

I have an old notebook with a bios memory bug, to boot it successfully I
had to pass mem=2000M to the kernel, otherwise it will start work suuuuuper
slow, 10-50x times slower.

Same problem with grub - to start it takes 60 seconds and every second in
the countdown timer lasts for 5 or more.

Recently I discovered the 'cutmem' command but it has a lack of
documentation and is not working as excected. When I issue 'cutmem 2000M
2040M' grub still works very slow and it does not fix the performance
problem. Can anyone suggest another solution?

BTW grub-legacy works fast!
