I checked in a patch that should help. Can you give it a shot?

revision 1.44
date: 2025-10-18 22:15:45 -0300;  author: jmcneill;  state: Exp;  lines: +10 -3;  commitid: vHCZXTlZiGEnk7fG;
bwi: Retry SDIO common regwin probe a few times before giving up.

It seems that on some systems, we need to read the SDIO common regwin ID
register more than once to properly identify it. Try a couple of times
before giving up.

This makes bwi(4) attach on my red Wii.
