This helps! now i can go up to kern.seedenable: 0 -> 1, and type
spaces there. If i try to do C-c it hangs again.

This time i can enter at the debugger before pressing C-c, so if you
want that i try something from there just ask. A trace will not help
because you would get just the keyboard interrupt, not the acpi code.

Entering on the debugger and going out of it made the system boot.

Also I noticed this warnings that may be important:

ACPI Warning (evmisc-0603): Cannont release the ACPI Global Lock, it has not been
acquired [20060912]
ACPI Exception (exutils-0425): AE_NOT_ACQUIRED, Could not release ACPI Global Lock [20060912]
ACPI Exception (exutils-0382): AE_TIME, Could not acquire Global Lock [20060912]

You can find the (non-verbose) dmesg with new acpi here[1].
