I think that it is highly likely that the Wii will still need a hardware mod in order to run Wii Linux (or the enevitable new Wii Channels) so this will probably not cause much damage to the Wii ...
The PS2 and XBox in the previous generation (and the Gamecube to a lesser extent) had similar possibilities and only the minority of users took advantage of them; the PSP is different mainly because the ability to hack the PSP without a mod chip is one of the main reasons people buy a PSP.
