Great clue here, Gary. Thanks!

Right. As I mentioned. I'm using the same kernconf I used to build the kernel
I'm currently using. dmesg(8) reports:
smbios0: <System Management BIOS> at iomem 0x40084000-0x4008401e
smbios0: Version: 3.3, BCD Revision: 3.3
ichsmb0: <Intel Alder Lake SMBus controller> port 0xefa0-0xefbf mem 
0x6001144000-0x60011440ff at device 31.4 on pci0
smbus0: <System Management Bus> on ichsmb0

So it appears that my system uses it. Now, if I can only get my OS to
provide it. ;)

Thanks for that great clue and all your time here, Gary!
