What's Arch got to do with OpenVZ RHEL based kernel? Red Hat backports different functionality into RHEL kernel and the thing you're using is far far from plain vanilla 2.6.32 or any other distro's 2.6.32.
Anyway, RHEL 6 does have trim support, simply refer to the relevant docs: https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/newmds-ssdtuning.html There's also a myriad of how-to's on the net about RHEL and SSDs... There are also Proxmox threads about SSDs and Debian converted OpenVZ RHEL kernels, if that's what you're using.
