Actually from what I have managed to gather, they will be using a virtual machine. I believe it is called Garnet VM and might be downloaded as source code seperate from the OS. I understand that Access Linux might be open sourced as well. I think Access is trying like Nokia to use as many "off the shelf" OSS apps as possible. The specs if memory serves were for a 220 meg processor with a small footprint in RAM. This would be wonderfull it it were compatible with the Maemo platform, but there might be problems with audio and text entry.
I for one, would be very happy if some of my Palm apps were portable via the virtual machine. I think that the aps which look decent on the larger screen of the Palm TX would be OK on the Nokia. particularily my palm office suite which copes with word processor and spreadsheet (.doc and.xls) files and is only about 5 MB. There is also a great solataire palm game which would be nice. Aeroplayer with ogg support for music. And last, but not least, the Palm Bejeweled game which I at least have a chance at. I haven't been able to beat Battlejeweled yet :-)
