ouch! rootcrs.pl, more than 64 CPUs => ORA-04031 when creating the ASM instance

back from holidays and the first ouch on the first day. we tried to setup a clustered grid infrastructure on a solaris 10 t4-2 machine. business as usual, one might think. but when running the rootcrs.pl setup script asmca ( which in invoked from rootcrs.pl automatically ) reports:

...
main] [ 2012-11-02 12:58:59.282 MET ] [OracleHome.getVersion:1023] Current version from sqlplus: 11.2.0.3.0
[main] [ 2012-11-02 12:58:59.282 MET ] [UsmcaLogger.logInfo:143] Role SYSASM
[main] [ 2012-11-02 12:58:59.282 MET ] [UsmcaLogger.logInfo:143] OS Auth true
[main] [ 2012-11-02 12:59:21.347 MET ] [SQLEngine.done:2189] Done called
[main] [ 2012-11-02 12:59:21.349 MET ] [USMInstance.configureLocalASM:3033] ORA-04031: unable to allocate 32 bytes of shared memory ("shared pool","SELECT DECODE(null,'','Total...","SQLA","tmp")
...

hm. there is a support note about this behaviour ( 1416083.1 ) but there is no way to give asm parameters to rootcrs.pl or the crsconfig_params files. what we needed to do:
disable some CPUs ( so there are less than 64 available ), re-configure the cluster, adjust the asm memory parameters and then enable the cpus again. this seems to be the only workaround at the moment ( 11.2.0.4 and 12.1 should contain a fix for this ).
