OK, I FINALLY found the sample code in the Palm knowledge base. They appear to recommend NOT using WinCreateOffscreenWindow, and instead create a V3 bitmap and wrap it.
But they also access structures internally, and use the memNewChunkFlagAllowLarge flag with MemChunkNew to create buffers. While the demo code says it is designed from PalmOS5.0/5.1, I have seen posts of people that say they memNewChunkFlagAllowLarge flag didn't work when called from Pace. But I guess I'll just have to try this stuff and see.
It just seems though that Palm must have intended some high level way to allocate a huge bitmap without getting into the internals.
Look at MemGluePtrNew in the new Palm OS 68K 5.0 SDK R2 in the developer seeding area.
