Hm, I don't think so. OVMF includes CpuS3DataDxe with SMM_REQUIRE=TRUE only. My understanding is that the reporter encountered the issue with CSM_ENABLE=TRUE, SMM_REQUIRE=FALSE. I think OVMF should be recompiled with DEBUG_POOL and DEBUG_PAGE set in PcdDebugPrintErrorLevel. Then the OVMF log might expose the driver that allocates memory under 640 KB (so that LegacyBiosDxe cannot allocate 32KB (i.e., PcdEbdaReservedMemorySize) at 608 KB later).
