do you mean "boot -v"? :) It runs very fast, and there are not so much lines on the screen (is it possible to change screen reoslution before loading i915kms?)
Ok, now I've recorded cold boot without SD, without verbose, with my phone (yes, screenshots by photocamera, I fell so low!) and I was wrong, there is rtsx0:
rtsx0: <2.0c .....>
rtsx0: Card present
mmc0: <MMC/SD bus> on rtsx0
rtsx0: Interrupt card inserted/removed
rtsx0: Card absent
PANIC! (without rtsx0 in stacktrace, again it is run_interrupt_driven_config_hooks()).

Oooops, keyboard is unresponsive after first pause and I can not unpause output :-(
Looks like another bug of early boot — EFI boot can not access keywboard before it is detected as `atkbd` (keyboard in loader works!)
