Thanks, JohnC, for the reply. I've read most of the posts but thought there might be a 'real' solution by now. I have tried the editing the .inf, as suggested here, following by creating a separate addon for installation of the control panel and the integration appeared to work fine - the control panel integration seemed to work as well (XPx86 SP3). However, I'm having occasional BSOD's that I suspect may be related to the mods I've made so I was hoping there might be a better solution out there. If not, I may just go back to 182.50 which seemed to work fine.
