Sorry, stupid mistake on my part.

In gpioirq() in "case DATA_BMP_LOAD:" add:

                if (len>6*1024)
                        len=6*1024;


here is were it goes:

        case DATA_BMP_LOAD:
        {

	...


                if (len>dvb->bmplen)
                        len=dvb->bmplen;
                if (len>6*1024)             // ADD THESE
                        len=6*1024;         // 2 LINES!!!
                iwdebi(dvb, DEBINOSWAP, IRQ_STATE_EXT, len, 2);
                memcpy(dvb->saa->debi, dvb->bmpbuf+dvb->bmpp, len);

	...
}

(Sorry, due to other driver changes a diff produced too much/unusable output)
