    BTW, I should mention that, with a TMCLK of 33000 (very common,
    because it's just the PCI bus clock), increasing the limit from 300000
    to 1000000 us actually increases the “counter” value by exactly 1
    (from 11 to 12). This is probably why the older controller-specific
    hack of simply incrementing the counter worked.
