Just to reconfirm, that all regions in Russia kept time zones unchanged (plus DST). Irkutsk didnt't switched to Krasnoyarsk Time Zone.
Here are 4 maps with Russian Time Zones in relation to World Time Zones (for example, Moscow Time Zone UTC+3 green color will be UTC+4 blue color during winter time):

I won't be surprised if there will be additional time adjustments in Russia by winter 2011. Otherwise, for example, Kaliningrad Time zone UTC+3 will be the only time zone in Europe (when DST ends in Europe on Oct 30, 2011) surrounded by nearby regions (Poland UTC+1 and Lithuania UTC+2)...

There is a proposal in State Duma to adopt Russian new Bill 509727-5 "On the Calculation of time" on April 19, 2011. The document, among other things, will provide the legislation to abolish Daylight Saving Time in Russia.
