At91 SPI Driver is broken... Or has at least changed the way it works...

I usesd the AT91-SPI driver last year for accessing two devices which 
are using 24-bit data-words. My working code looked like this:

    ...
    cyg_spi_transaction_begin(spi_device);

    HAL_WRITE_UINT32(AT91_PIO + AT91_PIO_SODR,               PA_SSPLL | 
PA_SSDDS | PA_SSIQ0 | PA_SSIQ1);
    HAL_WRITE_UINT32(AT91_PIO + AT91_PIO_CODR,     device & (PA_SSPLL | 
PA_SSDDS | PA_SSIQ0 | PA_SSIQ1));

    cyg_spi_transaction_transfer(spi_device, false, send_size, send, 
NULL, false);

    HAL_WRITE_UINT32(AT91_PIO + AT91_PIO_SODR,               PA_SSPLL | 
PA_SSDDS | PA_SSIQ0 | PA_SSIQ1);

    cyg_spi_transaction_end(spi_device);
    ...

Now i have a newer version of eCOS and this code dosnt beave good 
anymore. The problem is, that the CS goes between every byte, thus my 
devices get not 24-bit-words but 3 times a 8-bit-word. So my SW doesent 
work anymore, and i need to know. if i have to fix the driver and make a 
patch, or if the driver is ok, and i have to change the way i use the 
SPI-infrastructur...

Thanks for answers
