What was the first stable Debian release that enabled PAE support (bigmem kernel option)? Is it enabled by default in Debian6?

Squeeze (6.0) has a -bigmem kernel flavour, so it is available, but not
default.

I don't know which was the first stable release with PAE support, but I
seem to recall even sarge (3.1) had it.

Kind regards,
Andrei

The first?

If we take we time-machine and according to the snapshot archive¹, there
was a "-bigmem" kernel since 2.6.17 (dated on August 13th, 2006) which
means... Sarge, then? :-?

It will be from Wheezy, AFAIK.

In earlier versions... Mmm, I would better look at the image ISO content
to see what's included in each of them, for instance:

http://cdimage.debian.org/debian-cd/6.0.4/i386/list-cd/
http://cdimage.debian.org/debian-cd/6.0.4/i386/list-dvd/

Which seems to indicate the first CD does not contain the bigmem kernel
while it is present in the first of the DVDs. If the kernel is there it
may be preseded and thus triggered to be available at install time, at
least when using the expert installer.

One additional point, one can still install Debian without 'bigmem' support,,,,
then install the correct kernel for your hardware, you just won't see all the
memory during the install.

Yes, that's the default behaviour, I guess.

It would be nice though, that Squeeze installer could detect the CPU
capabilities and gives the user the possibility to install all the
available kernels for the 32-bits flavour: "-486" (non PAE, non-SMP),
"-686" (SMP, non-PAE) and "-bigmem" (SMP and PAE).
