[ewg] compat-rdma compile problem on OFED-3.5.2-rc3, on SLES11SP2

[Brian Ginsbach]

Hi Jeff,

Actually, it is worse than that.  Even later SLES 11 SP2 and SP3 kernels
(e.g. 3.0.101-0.5-default) won't fall into the SLES 11 specific section
since they are no longer named "Sneaky Weasel".

I'm working on a fix, but the problem is that according to a Novell wiki page I     was looking at, SP3 had an original kernel version of 3.0.76. Hence the valid kernel version ranges for SP2 and SP3 overlap.
