freeradius 0.9.3 capabilities

[energy at onedatacentral.com]

I am looking to perform certificate authentication for both external pptp
connected users and 802.1x wireless users. SLES 9 comes with FreeRadius
0.9.3. Does this version contain these capabilities or am I better off
upgrading? I know last time I upgraded a SuSE server the upgrade was not
fun. So I don't want to upgrade for "newer code is better" reasons, but to
achieve the goal of certificate use if required.
