It is my understanding that IrDA and the RCX use totally different
carrier frequencies for the IR ports, and thus are incompatible at
a much more basic hardware level. This has been discussed in great
detail in the past, so I recommend browsing the archives (available
on http://www.lugnet.com).
Why not hook up your Lego IR transmitter to your laptop/WinCE device
via the serial cable, and control it that way?
There was a team working on making a programmable IR remote for
some WinCE devices that I read about a few months ago, but they
had a very short list of supported hardware (think it was one or
two devices), because the others didn't offer the low-level carrier
frequency control required to talk at a standard IR modulation
frequency.
