Click on Hineinblättern and you can read almost all of it online. It's in German, but I'll have a skim through and see if there's anything on the transition to mounted infantry.

"Apart from the Guard Cavalry Division, the Cavalry was deployed in brigades attached to Infantry Divisions, but upon mobilization most were grouped into 11 Cavalry Divisions organized in Corps of 2 or 3 divisions plus Jäger battalions, with the remainder allocated to the Infantry as divisional cavalry. . . . Although the Divisional Cavalry attached to the Infantry remained mounted, more than 80% of the remainder was progressively dismounted and formed into Kavallerie Schützen (Cavalry Rifle) regiments, each of three battalions of 4 Rifle and 1 MG squadron." The MG Squadron appears to have had 6 heavy MGs and 4 Minenwerfer.
I take that to mean that these Divisions were used not as Mounted Infantry but as straightforward Infantry, rather as the French Cuirassiers were. Happy to bow to superior knowledge.
