It's rock solid here.
Lucky I just built 2.2.6. I'm building with your patch right now. It was a pain to get it building because your changes to arch/i386/Makefile broke the pentium & ppro configs for gcc 2.7.2.3 - this version of gcc doesn't support -mpentium & -mpentiumpro.
BTW, you have 128mb, right? With my test program you should experiment with the number of records. I'd think 120,000 records should be sufficient to bring the machine to its knees. 240,000 should definitely do it. At least it would on a 2.0 machine & probably would on a 2.2 machine.
