I use Resco Explorer to get the .pdb files out of my actual Palm device (TX) and on to a SD card. You can use the Install button in GVM (Hildon Window) to install the .pdb files. GVM "Install" (Hildon Window) will recognize the SD card, only once the actual virtual machine has been launched does the ability to see your SD card go away. This is the same way I've installed all of my Palm apps on my N810. Have you hotsync'd to install your apps?
