I have not heard of any. However, IIRC some of the points programs have been done in Excel. There are many Excel-compatible Palm spreadsheets, so it's possible that one of them may run.
I have a Garmin iQue 3600 Palm/GPS combo, and run DocumentsToGo. It keeps Excel in its native format, not converting from Excel to Palm and back, so it might be a good bet.
Now if only I can remember what points program is in Excel...
