Yes, discovered this little doosey a few days ago
Here's what I used:
My Sky HD box
My genuine Sky sub card
A White UK FTV card [link deleted - ICDG]
Here's how I did it:
Plugged out my Sky HD box, inserted the FTV card, plugged it back in and switched it on.
Changed channel to 105 (Channel 5) and switched off box.
Put back in my normal Sky sub card switched it on and viola Channel 5 and BBC One HD on the EPG!
Weirdly 3e and Channel 5 are both on channel number 105 and also BBC HD and BBC One HD are on 143.
All the Sky+ pause, rewind record functions work as normal, haven't tried Series link yet.
Discovered this trick 2 days ago and has worked ever since, channels seem to remain until the box is plugged out, will do a bit more testing including series link. Could be a great find for those looking to record the new BB
It turns out that if you have the correct regional variations of ITV, ITV 2 etc stored in other channels (that match your FTV card) then these will also be added. I now have all the ITV's including ITV HD
