For DRM-free e-books FBReader is best, but for DRM-laden e-books the Palm emulator is your only option (other than breaking the DRM, e.g. of a LIT e-book). I tested MobiPocket reader, and my only complaint was that the 320x480 resolution only uses 40% of the screen. See
Palm Garnet VM now available for Nokia N770, N800, N810. There are probably bible-specific applications for Palm, which should also work.
