So, for the archives: I have compiled the newest OVMF git master in the DEBUG mode and found out that under normal qemu both I/O debug port 0x402 logging or serial port logging (depending how OVMF got compiled) do work. I have never been getting debug output from the OVMF started by Xen. What I didn't know is that firmware images are compiled into the hvmloader so that just replacing the ovmf.bin DOES NOT work. I must have had a 32-bit ovmf.bin on the filesystem when I was compiling xen-tools; after replacing it with a 64-bit version and rebuilding xen-tools things started to work. Sorry for noise!
