WRT610N incompatible with Bonjour

Question

I read an earlier posting about an issue between SPI on the latest WRT610N Version 1.0 firmware and a user's Apple TV. This pointed me to a "solution" to a perplexing problem I was having.
I have 4 machines, 3 connected via WiFi and 1 on one of the wired ethernet ports. I also have 2 Apple Airport Express units for audio streaming as well as 2 iPhones connected wirelessly.
Now for the symptoms, which are all new since updating to firmware ver.1.00.03.15:
1. The WiFi machines see the Airport Express units and can stream audio to them. However, the iPhone Remote app has trouble staying connected to iTunes running on any of these machines.   A router reboot is a temporary fix, but connection is eventually lost again.
2. The wired machine cannot see the Airport Express units, nor can the Remote app pair with iTunes on that machine. It's as though no Bonjour-related functions work. Here, a router reboot also provides a temporary fix, but one that lasts only minutes.
Based on that prior post, I disabled SPI on the router and, lo and behold, the wired machine suddenly sees all Airport Express units and can pair with the iPhone Remote app!
I was going crazy, verifying that I was not having Windows Firewall issues, that there wasn't an incompatibility with Windows 7 (which I'm running on all), that this wasn't a Homegroup incompatibility of some sort, that Bonjour was up to date, etc. Only turning off SPI fixed the problem entirely.
So, Linksys ... can you shed light on this issue? Any firmware bug fix in the works for this? Can I safely go back to the prior firmware update without security or function concerns? If so, where can I get my hands on the older firmware file?
Thanks,
David

LINKSYS, PLEASE READ THIS ENTIRE THREAD!!!! 
I had the exact issues described here with the WRT610N and trying to get the iPhone Remote app to pair and consistently work.  I too thought I had narrowed the problem down to the SPI firewall only to have the problem return an hour later.  I called the worthless Linksys tech support only to be told that I had set something incorrectly and to reset the router.  I did that and still had the problem.  At this point I got the old "well it must be Apple's problem then . . . call them" response (In a bored, foreign accent of course).  Honestly, I would rather Linksys not provide support at all then to provide the terrible support that they do.  My WRT610N went back to the store after this.
I am both sad and glad to see that others are having this problem, though I seriously doubt that the decision makers at Linksys will ever hear about it.  Like most other tech companies today, the people who can actually make a difference and, God forbid, HELP the customers have insulated themselves so far AWAY from the customers that it is impossible to make our complaints heard or to submit a bug.  Of course, in there eyes, all customers are stupid and 100% of problems can be solved by resetting the modem, the router, and the computer.  If that doesn't work, it's someone elses fault.
