Atually, it's been part of the stock Linux kernel for years (probably
already in 2.4). In Debian, you just need to install the
linux-image-<vers>-686-bigmem rather than linux-image-<vers>-686
package. That's it. No known compatibility issue. The only "problems"
with it is that if you look under the hook, you may feel like it's a bit
of a hack, and also that in some micro benchmarks you may find such
kernels to be marginally slower. No big deal, really.
In that case, as installation disks (I think) automatically sense the
CPU, and install the appropriate kernel for the CPU, does an
installation disk automatically find how much RAM a computer has,
It's in /proc/meminfo.
then install the appropriate memory size based kernel?
The CD ISOs are pretty space-constrained. You could file a wishlist
bug report, but the D-I team would probably prioritize it low.
