Just installed using Wheezy installer on an older IBM Thinkpad Z61and a newer Lenovo Thinkpad X121 The Z61 needs no firmware to work out of the box.
The X121 was installed using UEFI (over a previous UEFI install) so not partitioning the disk ab initio.
The X121 needs libdrm1-radeon and nonfree firmware (brcm80211 to cope with the Broadcom wireless chipset).
The new UEFI installer splash screens worked very well indeed and I'm very impressed. An expert install extended to also install a KDE desktop worked like a charm. Many thanks indeed to all who've been so hard working on this especially Steve for the initial UEFI work.
