[gentoo-hardened] PAX in gentoo incompatible with AMD K6II processors? (PAGEEXEC vs SEGMEXEC)

[Julian Rendell]

I've just come across the following page:
http://d-sbd.alioth.debian.org/www/?page=pax
which states:
On i386, there is no NX bit in hardware; thus, one is emulated for a
nominal cost. There are two emulation methods, PAGEEXEC and SEGMEXEC.
Each method has its own faults and its own merits. It should be noted,
however, that on k6-2, PAGEEXEC cannot properly function and SHOULD
NOT be enabled. This is due to the k6-2 having a different TLB
architecture which in most cases is compatible with other i386
processors; the advanced use that PAGEEXEC makes of the TLB is NOT
compatible with the k6-2 TLB architecture.

Is the hardened tool-chain set to use PageExec?
If so, how can I change it to use SEGMEXEC?
Are there any stages pre-compiled with SEGMEXEC?

Thanks in advance,

Julian
