Yeah, I saw that.  Same time in my inbox, too. ;^)

It says on the front of the case "IBM eserver", but the "e" sort of
looks like an "@".  Also printed on the front of the case is "x220."

I have no idea if there is a service processor installed in the box.

Here is the output of lspci:

00:00.0 Host bridge: ServerWorks CNB20LE Host Bridge (rev 06)
00:00.1 Host bridge: ServerWorks CNB20LE Host Bridge (rev 06)
00:01.0 VGA compatible controller: S3 Inc. Savage 4 (rev 04)
00:09.0 Ethernet controller: Intel Corp. 82557/8/9 [Ethernet Pro 100]
(rev 08)
00:0f.0 ISA bridge: ServerWorks OSB4 South Bridge (rev 50)
00:0f.1 IDE interface: ServerWorks OSB4 IDE Controller
00:0f.2 USB Controller: ServerWorks OSB4/CSB5 OHCI USB Controller (rev
04)
01:03.0 SCSI storage controller: Adaptec AIC-7892P U160/m (rev 02)

There is a 2nd Intel e100 interface on the motherboard ("planar" in
IBM-speak), but that has been set to "disabled" in the BIOS for some
reason.  Re-enabling it has no effect on the time skew, nor does the USB
legacy support that worked for someone else on a different system.

Strange, huh?
