Does fxp works with PAE in 6-STABLE? Is TWE stable in PAE?

[Artem Kuchin]

I have read that in 5.x fxp driver did not work with PAE, but,
as i see, fxp is not in 'nodevice' section of PAE kernel config anymore.

Is it okay now to use fpx in PAE kernel? 
Also, is twe driver very stable in PAE?

I have a web server with 6 gigs of RAM and would like to use them all.

Thanks,
Artem
