Nope, I wanted to confirm if its same or not.  I have heard/thought I saw it was different.

For MC30xx (MPA1.0) the following REG key was used to prevent the SDMMC drivers from being unloaded on suspend/resume:

[HKEY_LOCAL_MACHINE\Drivers\Builtin\sdmmcloader]

''NoRemoveOnResume''=dword:1

and for MC31xx (MPA 2.0) the following registry.

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\SDHC_GENERIC]

"NoRemoveOnResume"=dword:00000001

As both 31xx & 95xx are based on same platform MPA 2.0, the same registry used for MC31xx may help.
