Yes, I saw that.
There are indeed some ACPI related warning messages.
[ 2355.912119] ACPI Warning: \_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type
mismatch - Found [Buffer], ACPI requires [Package] (20140926/nsarguments-95)
[ 2355.912786] ACPI Warning: \_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type
mismatch - Found [Buffer], ACPI requires [Package] (20140926/nsarguments-95)
[ 2357.181414] thinkpad_acpi: EC reports that Thermal Table has changed

But the ACPI warning is generated when graphics _DSM is invoked, and the
thinkpad_acpi one is sounds like a platform driver issue.
Thus I don't see what we Linux/ACPI can do for this issue.

IMO, nomodeset makes the problem disappear is sufficient to show that this is a
graphics issue, but to double check if it is a thermal issue, you can build
your kernel with CONFIG_THERMAL=n and boot without nomodeset parameter and
check if the problem still exists.
