After updating several machines to 2.6.20, I can't boot anymore the single one of them that supports the NX bit and is configured as a 32-bit system. My understanding is that the VDSO changes in 2.6.20-rc7 were not fully cooked, in that with that config option enabled VDSO_SYM(x) now equals x, meaning that an address in the fixmap area is now being passed to apps via AT_SYSINFO. However, the page is mapped with PAGE_READONLY rather than PAGE_READONLY_EXEC. I'm not certain whether having app code go through the fixmap area is intended, but in case it is here is the simple patch that makes things work again.
