Thanks Idwer for your response.
I downloaded most public datasheets available for the CPU and the PCH (it was called 7 Series).
At this point I'm mostly interested in just identifying the flash chip without disassembling the laptop, although I'm ready for that if necessary.
However, I do need to find a USB-based chip programmer that can do parallel, FWH and SPI. I still have to get a spare SPI flash chip and port coreboot to my Asus AMD board. For some reason I killed by home-built Willem PCB3B trying to convert it to PCB4-something to use newer version of its software.

Hi all,
I'm back. With a new laptop.
I'm now rocking a Lenovo x230 tablet, dual-booting Windows 7 and Fuduntu, both 64-bit. Knowing the last time I contributed to coreboot it was the good old 440BX when life was much simpler, it could be a while before I can get up to speed again, so I'll for now just put forth the obligatory lspci/superiotool dump to give any interested parties a heads-up of what support needs to be programmed for.
Another interesting thing is it does UEFI.
Below is output of flashrom 0.9.6.1. I cannot get it to identify the flash chip. lspci and superiotool dumps are attached.
This thread mentions that it runs QM77: http://forums.lenovo.com/t5/X-Series-Tablet-ThinkPad-Laptops/X230-Tablet-Chi...

Thanks. ======================================================================== WARNING! You seem to be running flashrom on an unsupported laptop. Laptops, notebooks and netbooks are difficult to support and we recommend to use the vendor flashing utility. The embedded controller (EC) in these machines often interacts badly with flashing. See http://www.flashrom.org/Laptops for details.
Also, see the "Laptops" section in flashrom's man page.
If flash is shared with the EC, erase is guaranteed to brick your laptop and write may brick your laptop. Read and probe may irritate your EC and cause fan failure, backlight failure and sudden poweroff. You have been warned. ======================================================================== Aborting. Error: Programmer initialization failed.
You'll want to do a little investigation on which external programmer [1] suits your needs.
