They are indeed perfectly hackable for HBC purposes. However they wont work with "softmod" tuorials i.e. softfail tutorials. This is because I believe they brick if they have downgraded IOS or something. I dont really understand it. But there are now "fixes" for these Wii's and people can "softmod" their LU64 Wiis, leading to an influx in the number of fail tutorials on GBAFail's "Wii Hacking" forum. It's actually kinda funny how many people post "the ULTIMATE guide to softmod" or similar title (always with ultimate in caps).
But basically, for legal purposes, you can do pretty much anything on these Wiis, besides install BootMii as boot2, but that is just recent Wiis in general, not specifically these "unsoftmoddable" ones, which are only LU64+ Wiis I believe.
EDIT: It appears the "fix" is a hacked bootmii sd card setup, and bootmii IOS. i will not discuss such things here of course, but it seems that with this, most "softmod" stuff is possible. by which i mean you can stuff your wii full of fail.
