I can verify, that booting via grub 2 works like it should in UEFI mode.
The amd64 version of Ubuntu Wily daily iso file 'ubuntu-wily-desktop-amd64.iso' is still affected by this bug, the syslinux boot error. This is in BIOS mode.
I checked today in UEFI mode, and a pendrive made with the SDC in Wily and from Wily can boot (and it uses grub 2).
