Hi,
Sorry to be slow in replying. I was out for a while.
I suspect that you need the firmware upgrade, regardless of what the release notes say. I'm thinking that just about all of these consumer-grade broadband routers were flakey when running their first incarnations of their firmware under WinXP. I think many of the problems may have had something to do with the TCP/IP stack implementation of WinXP not getting along with the firmware.
If I'm understanding your intentions regarding dual booting, yes that should work. There's really no functional difference between installing Win2K on the first physical drive and WinXP on the second physical drive and simply installing Win2K on the first partition of a given physical drive and WinXP on the second partition of that drive. WinXP will place its own boot loader files and make the appropriate changes to the MBR on the first physical drive. The boot.ini file will be written in such a manner as to produce a boot menu for you so that you can choose between operating systems at boot time. You must simply remember that if you ever have to perform a repair on the Win2K installation, you will then have to perform a repair on the WinXP installation. That's because the Win2K repair procedure will replace the WinXP boot loaders with its own, and those won't work for booting WinXP.
I'll keep my fingers crossed for you and hope that this works out. I've found networking with WinXP to be extremely solid. I'm a relative newcomer to Windows, having started with it just before the release of Win2K. I was horrified by Win98SE and WinME, but have been very surprised and pleased by Win2K and WinXP. (I'm an old big iron and AIX / VMS guy, but I'm no snob.) I'm having the time of my life, information technology-wise, with WinXP. I think it show tremendous promise, and there are so many toys you can use with it!
