I will check in my patch.

I will post a patch to remove "general" from missing registers.
As for void * registers, we always print
(top-gdb) maint print register-groups
Name Nr Rel Offset Size Type Groups
eax 0 0 0 4 int general,all,save,restore
ecx 1 1 4 4 int general,all,save,restore
edx 2 2 8 4 int general,all,save,restore
ebx 3 3 12 4 int general,all,save,restore
esp 4 4 16 4 *1 general,all,save,restore
ebp 5 5 20 4 *1 general,all,save,restore
esi 6 6 24 4 int general,all,save,restore
edi 7 7 28 4 int general,all,save,restore
eip 8 8 32 4 *1 general,all,save,restore
