I've replaced two files in /usr/src/sys/dev/rtsx, rebuilt GENERIC kernel and it boots!

  Output WITHOUT card is like this:

pci2: <ACPI PCI bus> on pcib2
rtsx0: <2.0g Realtek RTS5227 PCI MMC/SD Card Reader> mem 0xf4500000-0xf4500fff at device 0.0 on pci2
rtsx0: We are running with inversion: 0
rtsx0: Interrupt card inserted/removed
rtsx0: Card absent
rtsx0: No card is detected
pcib3: <ACPI PCI-PCI bridge> at device 28.1 on pci0


  Output WITH card is like this:

pci2: <ACPI PCI bus> on pcib2
rtsx0: <2.0g Realtek RTS5227 PCI MMC/SD Card Reader> mem 0xf4500000-0xf4500fff at device 0.0 on pci2

...

  No visible delays in both cases.

  Both boots are "cold", with AC cycle
