PAE kernel on 1GB system?

[Ian Pilcher]

I am setting up a fanless 1GB VIA C7 system to run Asterisk.  (It also
has a 32GB SSD -- no moving parts at all!)  By default anaconda uses the
i686 PAE kernel for this system, presumably because the C7 instruction
set qualifies it as an i686.

I can't think of any reason to use a PAE kernel on this system, so I'm
thinking of switching to the i586 kernel.  Can anyone see any
disadvantage to making the switch?

Any problem using the i686 versions of glibc, openssl, and any other
userspace packages?

Thanks!
