IDNs recognized by search engines?

Registries promoting IDNs - which search engines recognize them?

[nonanet]

There seems to be some movement in the IDN space - IE7, which supports IDN, should be out in the foreseeable future, and registries start to promote IDNs as well (eg. .at-IDNs free in the first year).

However, what major search engines will recognize IDNs (where i'd put "recognize" that they display the domain name with the non-ASCII characters with search results, rather than the ugly punycode)? My own IDN does not yet show up in search engines, so i couldn't test it...

Has anybody already put together a survey that i've missed?

Google , Msn and Yahoo allready show IDN Domains in they're Unicode format ("normal"..not with the xn--etc Punycode)
