Control Panel applets can also be registered in "HKCU\Control Panel\MMCPL".

Well, technically, they would be registered in the [mmcpl] section of 
control.ini, which is then mapped in the registry 
(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows 
NT\CurrentVersion\IniFileMapping\control.ini) to the appropriate registry 
entry. However, as far as I can tell, Wine's profile string functions don't 
currently support INI file mapping (there's a patch on the bug tracker, but 
it was never accepted, it seems), so if any old application did try to write 
to the control.ini file, it wouldn't end up in the registry. I could add a 
check for CPL entries in control.ini if desired using the 
GetPrivateProfileSection function, and if/when Wine does support INI file 
mapping, the code wouldn't then need updating to point to the "right" place.

That sounds like the right way to do it.

.ini file mappings are on Alexandre's todo list, fwiw:

While they may be registered there as well, I'm pretty sure that some
versions of Microsoft Office register control panel applets in the key
I mentioned.

Well, yes - what I meant is that the key at 
HKLM\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\IniFileMapping\control.ini 
maps any requests for control.ini, section [mmcpl] to HKCU\Control 
Panel\MMCPL.
