Yes. With wifi disabled in the BIOS, the laptop boots both with and without a card inserted.

Booting a recent GENERIC with the following /boot/loader.conf

#dev.rtsx.0.inversion="1"
kern.geom.label.disk_ident.enable="0"
kern.geom.label.gptid.enable="0"
kern.geom.label.disk_ident.enable="0"
kern.geom.label.gptid.enable="0"
cryptodev_load="YES"
zfs_load=“YES"

uname -a:

Booting with card inserted, wifi enabled in BIOS succeeds.

Booting with no card inserted wifi enabled in BIOS fails.

Booting with a card insert wifi enabled in BIOS succeeds.

Booting with no card inserted with wifi disabled in BIOS succeeds

The dev.rtsx.0.inversion flag inverts the behaviour: With wifi enabled
booting fails with the card inserted and succeeds with no card inserted.
