Yes, the test bed sounds good and stable. I've been working with Fedora 
(mainly 6 and 7) and quagga ranging from 0.96 to 0.99.8 without problems.

Reading the patch you linked, there's something I see:

+#if defined(GNU_LINUX) && !defined(TCP_MD5SIG)
+
+/* XXX these will come from <linux/tcp.h> eventually */


Did you make sure TCP_MD5SIG is compiled with the kernel? Is the module 
loaded?
I don't recall if that's true for all kernels distributed with the 
distributions you mentioned.

Maybe you could download the source package for the kernel and make sure 
the TCP_MD5SIG is being compiled?

Or, if it is a module, trying to load it before running quagga?
