* SADC to be asked to mediate

(Adds details, background)

HARARE, May 21 (Reuters) - Zimbabwe's power-sharing government has resolved most disagreements but is deadlocked on the appointments of the attorney general and the central bank governor, whose tenure was marked by hyperinflation.

Prime Minister Morgan Tsvangirai said the regional Southern African Development Community (SADC) would be approached to mediate over the disputed posts.

The posts of central bank chief Gideon Gono, a Mugabe ally, and that of the attorney general have been the most contentious in the fragile unity government formed by President Robert Mugabe and Tsvangirai in February.

Critics say Gono printed money, pushing inflation to the world's highest levels and undermining the local currency, and raided private bank accounts to shore up Mugabe's past regime.

Donors have expressed disquiet over Gono's continued presence at the central bank while rights groups accuse the attorney general of presiding over the prosecution of rights and opposition activists.

"In light of the above, and the fact that there is a deadlock on the status of the two individuals in question, the principals, with the support of our parties, will now refer this matter to SADC as the guarantors of the GPA (Global Political Agreement)," Tsvangirai told a news conference.

The agreement was signed in September last year and paved the way for the creation of the power-sharing government.

Tsvangirai said all other outstanding issues had been resolved, including the appointment of senior government officials, ambassadors, provincial governors and the swearing of Roy Bennett, a senior white MDC official, as a deputy agriculture minister.

Mugabe had refused to swear-in Roy Bennett because he faces terrorism charges, which the MDC says have no basis.

Four MDC appointees would be named ambassadors in five of the vacant posts while several other would undergo diplomatic training and would be appointed when vacancies become availaible.

Out of the ten posts for provincial governors -- a plump but influential job -- six would be retired and compensated. The MDC would appoint five, Mugabe's ZANU-PF four and the remaining one allocated to a smaller MDC faction.

The formation of the unity government has raised hopes that Zimbabwe could be on its way to recovering from a devastating decade of economic collapse and political tensions.

International donors, who are vital to the southern African country's recovery, remain sceptical and continue to withhold aid, demanding the new administration show commitment to political reforms and freedoms.

Tsvangirai said while the government had registered some success, he remained concerned about the continued violations of the rule of law, especially the seizure of white-owned farms.
