colin, can we please use the linux-lowlatency-pae kernel by default?

discussion for this decision:
[13:09] <micahg> scott-work: I think you might want the pae kernel for i386 as studio is targetted to beefier machines
[13:09] <scott-work> micahg: is there a downside to choosing pae?
[13:10] <micahg> the non-pae kernel on i386 means machines with >4GB RAM won't be able to address it
[13:10] <scott-work> right, but is there a sacrifice to using the pae?
[13:10] <micahg> the downside to pae is older machines and older laptops netbooks won't be able to boot off the image
[13:11] <scott-work> i wonder if we would start seeing bug reports of these machines not booting then :P
[13:11] <scott-work> i'm still leaning towards just keeping linux-lowlatency , to be honest
[13:11] <micahg> scott-work: upgrades would work, it's just the live DVD won't
[13:12] <micahg> it depends on who your audience is
[13:12] <scott-work> i believe our current kernel is not pae enabled, so in this regard we wouldn't be "changing"
[13:12] <micahg> people with more RAM just have an extra step to install the PAE kernel
[13:12] <scott-work> BUT, we will be giving them more performance
[13:12] <scott-work> hmmm
[13:13] <micahg> well, the default in 12.04 for i386 is the PAE kernel
[13:13] <scott-work> oh, hmmm
[13:13] <micahg> but you have the choice here
[13:13] <scott-work> okay, i'll tell cjwatson then
