Right then, to conclude... It seems the comment
/* Tweakable by config(8) */
in sys/arch/amd64/amd64/machdep.c is in error.
The variable can not be changed from config(8),
neither before kernel compilation nor on a compiled kernel.
And it can also not be changed from UKC via boot -c.
But it can certainly be changed by editing the line
in sys/arch/amd64/amd64/machdep.c to
int bigmem = 1;
and then compiling a kernel. And it can be temporarily
changed via boot -d as stated above by Ted.
Objections, anyone?
