Anyone here know the IBM Thinkpad A21 BIOS developers? Their EDD data is wrong. They're reporting the disk controller is at PCI device 00:1f.7 when it's really at 00:1f.1, which would confuse any Linux tool trying to make use of it.
Relevant portions of EDD device data, lspci, and dmidecode appended. If you can point me at the proper folks within IBM, I'd appreciate it. -Matt
