ROM is an old word. For the purposed of this discussion ROM=NVRAM. NVRAM is used for storage in both PalmOS Garnet and WM5. Execution takes place in the Dynamic heap in POS and Program Memory in WM (both normal SDRAM, like your desktop).
The Treo 650 has 32MB NVRAM (23MB available) and 32MB SDRAM. The NVRAM is used for storage, and the SDRAM is used for transient storage (the DBCACHE) and Execution (Dynamic heap).
The Treo 700w has 128MB NVRAM (60MB available) and 32MB SDRAM. The NVRAM is again used for storage, and the SDRAM for execution (like the ram on your desktop).
The problem people have with the Treo 700w is that while it has a 32MB SDRAM chip, all its contemporaries have 64MB SDRAM. As you may know from your desktop machine, it doesnt matter how much storage you have if you have too little ram. The shortage of ram is causing people to have to soft-reset their devices to reclaim memory. Thats not really desirable.
I hope that clears it up any confusion..
