in fact, the x64 version is only required if the user runs an browser that is x64. so far i know, the default browser under x64 systems is still x86. also, if we deploy both versions in the same module, someone could say that we are deploying things without the knowledge of the user. by me, i never will do that. as for flash player x64, it is still preview releases
In a 64-bit system there are two browsers installed: one in \Program Files\Internet Explorer (the 64-bit version) and one in \Program Files (x86)\Internet Explorer (the 32-bit version). Users are capable of selecting either for use. I'm not sure why you say the 32-bit is the default - I have not had it act that way. If the 64-bit version has been invoked and the user selects Microsoft Update - an error nessage appears saying to switch to the 32-bit version - is that what you're assuming is the default?
Anyway, because both versions are available to any user than knows where to look it only makes sense to offer both Java runtimes - just list them as separate items: 32-bit for one and 64-bit for the other.
Same for Adobe Flash if/when it goes final for the 64-bit version.
