[bitfolk] Upgrading to Wheezy

Hi everyone, I'm a bit late to the Wheezy upgrade party, but successfully got the job done over the weekend. This has been third dist-upgrade for this VPS, having started life as an Etch box :-) One minor gotcha for a VPS of this age is that it started out with a xen kernel image (my /boot dir still has an Etch era vmlinuz-2.6.18-6-xen-686 kernel), and Wheezy no longer provides a separate xen kernel (in fact, it would seem that a xen kernel image wasn't necessary in a domU in Squeeze). Switching over to the default kernel from the linux-image-686 meta package was therefore the way to go. This installs the 686-pae variant, although I note that the Bitfolk Wiki page suggests the 686-bigmem kernel, which has 4Gb+ memory support. Is there any particular benefit to running a bigmem kernel on a smaller VPS with less than 4GB RAM? -- Phil
